Okay let me start off by saying that this movie was pretty damn amazing! I mean my expectations so high and this movie delivered! I'm a big comic book fan but i've never liked reading supermn because i couldn't relate to him here i can! This is a great movie that everybody in my opinion should watch but i'm going to tell you why some reviews are giving it a bad score.
1. Lack of humor: I should state i like darker tones in comic book movies, some people do not. That is fine of course! marvel is producing a bunch of light hearted movies with lots of humor but i think DC in general wants a more grounded more this is real this could happen, the danger is real! Type of feel to their movies. Thats one reason. Also a smaller group hated how there was little spark between lois and clark but its an almost 3 hour movie lets leave the romance for the sequel to save time!
2.nostalgia: I will admit i'm 18 so when i saw the original superman i found it outdated ( before you go crazy i grew up in an age where all the effects seem real so watching an old movie kind of weirds me out) but i feel as if the other type of people hating this movie is just because its not the Christopher reeves superman that they love so much. This is a new take and different from those movies.
those seem to be the major dislikes for this movie! Other than that this is one of the best superhero movies i have seen in a long time and if those two things don't SEVERALLY matter to you then you should love this movie.
