Having had my expectations lowered from various reviews, I kind of knew what to expect going into this film so I turned my brain off (tried to anyway) and just enjoyed the ride...and I came out pleasantly surprised!
Pros: Owen and the raptors could've easily been super cheesy and dull but it was actually pulled off very well. Pratt is really able to sell that he had been working with these raptors for a long time. Pratt, as a whole, did a really great job. Bryce Dallas Howard also acted well and she looked gorgeous throughout the movie. Her character, Claire, also had the best arc out of all the characters. Irrfan Khan as Masrani was always interesting to watch. It was nice to see a suit actually be likable for once! Jake Johnson, of course, was awesome. The effects were done well, though I definitely agree there's an over reliance on CG. I think watching it in 3D helped alleviate that. The iRex was pretty creepy at first! I really like how they kept it hidden for most of its appearances. I also felt a bit of that original JP wonder when the kids were exploring the grassy fields in the gyrosphere. I dug most of the attractions and features of the park. Most of the action was well done, especially the climax. I also liked most of the homages to the original movie.
Cons: Hoskins (D'Onofrio) was just BAD and I don't just mean as an antagonist. His character was just not very compelling and any time I saw him on screen I kept thinking that there has to be a scene where he gets killed or eaten. I can't remember the last time I hated a character so much...and not in a good way. Sometimes you want the antagonist to die because the direction and actor did a great job (see El Brujo from Ron Howard's 'The Missing') but this one definitely felt like poor execution and miscast. If they wanted to portray a *****ey ex-military type they should've gotten someone like Bill Paxton. At least he'd be an entertaining/likeable *****e. The kids weren't horrible, but they didn't add much to the movie either. In the original JP, the kids had real personality and they felt like KIDS! They were very fleshed out, well rounded, and ultimately likable. Gray and Zach both feel very 1 dimensional and 'meh'. I get that Zach serves as a commentary on modern teens, but they could have also made him, ya know...interesting. He had almost no personality and he seemed very disinterested being in Jurassic World until he was able to get away from the babysitter. Then all of the sudden he did a 180 and was interested in EVERYTHING. I also get that Gray was supposed to be this movie's Tim but nothing really worked with him. I also didn't buy his crying when he talked about their parents. Speaking of...they could've done without that whole subplot. It really took away from the film.
I guess the biggest problem I had with the movie are the characterizations, er lack there of. Even Pratt's character, Owen, felt typical and almost too perfect. When he runs from the iRex he looks like the T-1000 with perfect form. At the end, when he's shooting at the iRex he performs almost every move with calculative perfection as if he's 3 steps ahead of his actions. I get that he's ex-military, but even soldiers stumble and make mistakes in the heat of the moment. It felt a little too much like he knew exactly what to do in each situation despite the circumstances going awry. The character of Claire also felt too typical and 1 dimensional despite her character having the best arc. And really...[BLACKOUT]outrunning a T-Rex in high heels??[/BLACKOUT] That part just made me laugh out loud because it was unintentionally funny. I shouldn't be doing that during what's supposed to be the most epic scene of the movie.
Despite some of the characters being interesting at first, mainly Owen and Claire, none of them feel fully fleshed out and unfortunately they become less interesting as the movie progresses. There were also instances where I thought to myself "why the hell would they do that?" The 2 instances I can remember are when [BLACKOUT]Zack waited till the 3 count to jump off the cliff (you're about to die! JUST FRIGGIN' JUMP!) and when Claire got up on a platform to look for the kids during the pterodactyl raid, making her stand out like a sore thumb. It's like she actually wanted to get snatched up by a pterodactyl.[/BLACKOUT] There were a number of events that just felt forced. Particularly, [BLACKOUT]iRex's death. Why would the Mosasaurus lunge onto the land at that particular moment?[/BLACKOUT] The script could've used 1 or 2 more rewrites and the characterization of the humans definitely needed more attention. I also didn't really care for the design of the iRex. I liked it's characteristics and features, but it was not aesthetically pleasing to me and in some instances it actually looked kinda goofy/funny. Also, a lot of the product placement was just obvious and in your face. Jake Johnson's commentary about Pepsisaurus or whatever was spot on.
In the end, I had a lot of fun watching the movie but it has some major flaws that prevent it from elevating to the classic status of original film. It's definitely a MUCH better movie than part 3 but I'm hesitant to say that it's better than the Lost World simply because I haven't seen that movie in quite some time and I honestly enjoyed Lost World more so than most people express. I'm definitely glad I saw it in theaters for the thrills, but because of the poor characterization and some scripting blunders, I don't care to see it in theaters again. It's definitely a fun and entertaining film but there is a severe lack of characterization and several missteps in the script. Jurassic World gets a 7 out of 10 from me.
I'm listening to the soundtrack right now and it sounds even better after you see the movie as the themes have memories attached. 
Hope you enjoy it as well.
