I do think a lot of them are being fair. Of course, some may be too attached to the Christopher Reeve movies to fully evaluate this one (I'm too attached to Raimi's Spider-Man to fully evaluate TASM), but I do believe they're being fair. I mean, I'm not a critic by any means, but I agree with what they say about Man of Steel. I was never a Superman fan. In fact, the only experience I have with Superman is from the Justice League animated series and the old Fleischer cartoons. I came into this movie prepared to accept anything I was given, even if it was different from my (not very well-informed) preconceptions of Superman. The film was very clunky for me. I never understood the new Superman's motivations. In fact, he changed very suddenly several times. One scene, he's talking with a preacher, clearly wounded and conflicted, and then the next one he's all super-confident and floating in front of the army. It was very jarring to me. And then there's his relationship with Lois Lane. I saw it as being a friendship. Throughout the film they were just getting to know each other, no flirting or anything. Then after he saves her they make out like they had been deeply in love and couldn't bear the though of losing the other one. I understand they're together in basically every other Superman story, but I was given no reason to believe there was anything romantic between them in this movie. Overall, I never felt anything for the film. Sure, I enjoyed the action, visuals, and music, but I never felt for any of the characters, and I firmly believe this is because the film gave me no reason to. I mean, I'm not a hardcore Superman fan, I've never hated him, so I was going in completely neutral, just getting to know him. If that doesn't say that the movie didn't sell his character well, I have no idea what does. I will admit that there were a few times where I started to get emotional (that music is amazing), but then the film would cut to another scene (usually an action scene or flashback) and cut off whatever I was feeling. I mean, I did like the film. I loved the way Krypton was presented (especially the idea of genetic engineering), I loved the score (I listen to it regularly), and the action was fun. I just wasn't given a lot of reason (almost none, actually) to care for the characters. So, in a very roundabout way, yes, the critics are being fair. I hear that the biggest criticism people have a problem with is "too much action," but I believe the critics actually mean "too little character development," as in they wanted some of the action to be replaced with character development. I agree.
