They have gone a bit overkill on the superhero front since 2000,probably because modern technology allows these movies to be done like people have always imagined.
They can get a bit monotonous,being filled with CGI,overblown and too noisy.
Although IMO,
Spiderman 2,Batman Begins and Iron Man (not seen Dark Knight yet) were modern movie classics,some of that movie magic going on there.
The rest were at least watchable enough (If just from a kiRAB standpoint) apart from Catwoman and The Punisher,which were awful.
