Compared to "Cremaster 4" and especially "Cremaster 1", "Cremaster 5" is something of an improvement. It's much less silly and pretentious than those previous installments, and the annoying symbolism is a little less annoying. Throughout, there are very good visuals, and some beautiful music, but it is highly flawed. It's far too long than it should be, and it does have its fair share of eye rolling artiness, but it's still fairly fascinating.
Unlike previous "Cremaster Cycle" films, there isn't too much for me to say about "Cremaster 5". It is neither good or bad enough to get a very lengthy, detailed review. Overall, it's a decent art film that could have been better if it was a bit shorter.
