It's funny, with this movie the critics mostly liked it but fans absolutely seemed to loathe it. Non-fans seem indifferent. I personally love Superman and Superman II. I thought this was an ok film. I certainly didn't hate it like most. I felt there was something missing. I also couldn't shake the feeling that Routh was doing his best Christopher Reeve impression instead of making the character his own.

I think it's pretty good. There are many little clever awesome moments scattered all over the film. Now come on, the piano playing thug with a clown tattoo on his head is something you don't forget. :)
Lois is a real bitch though, but it was fun hating her. I understand why she's so pissed at Superman, but why does she ignore Clark Kent like that? Just let this poor guy finish a single sentence or something.
I'm a little sad it has such a bad reputation, but I kind of see where the haters are coming from. Still, the acting is good, so is the cinematography, the plot is alright as well. Fun times. I certainly don't regret watching it. As a non-fan of Superman I enjoyed alright and would recommend to other non-fans.

Interesting portrait of the Man of Steel... he's less super and more man in this movie. But overall, the movie falls flat.
