Here's my full review:
Spiderman: Homecoming is....competent. The high school drama is well done, the action is pretty standard for a superhero movie (save for the unspectacular final act), the acting is great, and the script is middling at best.
I really got the John Hughes vibe they were going for with the film. You get the sense that Peter is living a real high school life, which gives the character the shot of reliability that most other superheroes lack. It also helps that the supporting cast (from Logan Marshall Green's likeable professor to the school reporters) feel like they could exist in real life. The whole high school portion of the film is so well done that I wish they spent more time with it. It just has great comedic/emotional potential that they should (hopefully) tap into in future films. That's the good news.
Now, for the parts I didn't really like: the superhero stuff. In general (coz I don't want to give spoilers away), this was the first time that I didn't really want Peter to suit up. Blame it on the suburban-setting action sequences, or the oftentimes dull villain, or the spotty CGI, but I just wasn't feeling it when he was Spidey. It felt too much like he was just Spidey so that he could be an Avenger. Also, the suit is um...not Spiderman-like. It doesn't feel like Peter actually did anything with the suit on his own and that all these enhancements are literally handed down on him. I mean, I get that they did this in service of the overall arc but the impact of that arc, too, gets taken away once you get to the final scene.
The suit and the Avengers arc leads me to my next criticism: a lack of responsibility to this Spiderman. Sure, I get it, he's supposed to be fun, but he does what he does because "if the bad things happen" and he's not there, "then that's on him". This is a line said by Peter himself in Civil War, but nowhere did I feel that he was doing it for this reason in Homecoming. There's a moment in this movie that could have been one of the best (if not the best) Spiderman moment ever put on film. But, the full impact of that moment didn't hit me it because that moment could have been so much better if they could have somehow shown that he's doing what he does because "with great power comes great responsibility".
However, having said that, there were great moments in there that genuinely made me chuckle. There's a goofiness that Holland brings to the role that (when paired with a good script, which this film sadly doesn't have) could have been really well done. As it stands though, that goofiness only shines through in some of the sequences. (Just as an aside, there is going to be a drinking game invented soon on how many times Peter/Spidey uses the word "awesome". It's not a thing you can ignore. He uses it a LOT.)
Overall, there are parts of this film that I absolutely loved. But, there were also parts that brought down my overall enjoyment. I get why critics and general moviegoers will love it though. It's made for them.
On an optimistic note, there is nothing in my criticisms that cannot be fixed in a upcoming movie. With a better screenplay, they can hopefully reinforce why Spiderman is Spiderman in the first place.
Rating: 6-6.5/10 (a solid 7 if I were a casual viewer)
