I recently saw this film and it was great. it has a few flaws but it makes up for it by having a sureal aproach to the whole thing, it's a very layered film, on one hand it feels like a satire of a super hero film that questions the artistic integrity of those kinda films, and on the other hand its also just an interesting story about and outdated actor battling his inner demons while trying to remain in the spotlight.
What made this movie good was that those 2 concepts were merged perfectly through a sureal view and a great performance by the actors. i especially like Edward Norton's performance. he basically played Tyler Durden but with a different spin.
