The trailers played up the action sequences and "escape plan" plot, but Sucker Punch would have been better as a Japan-only video game instead of a movie. The CGI effects are impressive, but the story is practically incomprehensible. The characters are flat cardboard and I couldn't care about any of them. The "Wise Man" character spouts platitudes as though they were true words of wisdom and has an annoying running gag. Watch on Blu-ray if you must.
Despite becoming hot Hollywood commodities over the past few years, comic book movies have had a spotty record of quality. Iron Man deftly balances straight-ahead Hollywood acting and action with nods to details that comic book fans will appreciate. Also, what sets this movie apart from other action films like Transformers is its willingness to let the actors act and develop character relationships rather than simply advancing the plot to the next CGI explosion. A great achievement, highly recommended.
