Sky Captain was ok, nothing special.
As far as LXG I actually like that movie, but I have never read the comic it is based on. BTW the whole submarine in Venice scene was what my brother said to me when bashing the film.
Umm, it's a movie based on a comic book (sorry "Graphic Novel"). You have the Invisible Man hanging out with Alan Quartermain, Mina Parker, Dorrian Gray, Capt. Nemo and Dr. Jekyll and the submarine scene is a big deal? Come on now, where is the suspension of disbelief?
