The people who call it horrible (specifically, ignorant people that only see comic movies because they feel like it an have no understanding of the character) are the ones who are ignorant to film making. For example, some kid in my school once said that he was pissed that Rocky lost the match in ROcky Balboa, which is why he thought it sucked. ROcky didn't win, but he whent the distance, which is all that matters. Basically, people like that won't say "oh this film was meh. It was dissapointing." They will say "oh this is the most horrible thing on earth."
And fanboys are ignorant for the fact that they can say Spider-Man 3 is such a great film, but yet Raimi did NOT do justice to Venom, Sandman, the symbiote, it ruined Uncle Ben's death, and above all, ALL three movies made Spider-Man into a *****.
What the d-bag said about Rocky Balboa, yah, that was idiotic, but at least Rocky Balboa made the Rocky series enjoyable, instead of having it end with Rocky V, which WAS a horrible mess. Spider-Man 3, the premise at the beginning made the movie awesome, and it was supposed to be spectacular with all its hype, but a total letdown and joined the ranks of other superhero adaptation third movies such as Batman Forever, Superman III, X3...
Sam Raimi might have understood the characters of Norman Osborn and changed up Otto Octavius to fit him in Spider-Man 2(which still bothers me how Doc Ock was sympathetic, a lesson Raimi should've learned beforehand, but you can't teach old dogs new tricks I suppose), but Sammy did God-awful changes for Sandy and Venom, which weren't even close as the comics, except for Marko's clothing, and Eddie Brock was more like Ultimate Eddie Brock.
I would know what is a good movie and what's not, and I'm not ignorant to film making, as I am majoring in motion pictures and television at Academy of Art University.
Perhaps Sam Raimi learned from his mistakes, perhaps Arad won't give in his two cents over who should be in the film, but then again, Raimi helped write the story, Raimi is the one who cut the better scenes and put in pointless scenes, Raimi is the one who decided to make the symbiote turn Peter into Gerald Way, or that *****e from Green Day.
That is why Spider-Man 3 was horrible. Certain scenes such as the birth of Sandman and the bell tower were amazing to watch, but having to sit through dance routines and boring-ass Kirsten Dunst only dumbs down the movie. Maguire, to me, was never a great Peter, Dunst is a terrible actress, and the only bright side of the movies were James Franco, and now he won't be in the fourth film.
