I always heard great things about Monty Python the movie but I never seen the movie myself.
I didn't quite get all or maybe most of the jokes, but it was still fun. Great music, total randomness and just strange things that keeps you awake.
Some complaints I heard are that the jokes are the same as the movie and I also heard some people went to sleep. The person I was with was a hardcore Monty Python fan, but said it was less than expected.
At the same time, the guy behind me was having the time of his life laughing at every joke or.. just a sentence. Possibly drunk.
It was "ok" nothing people gave a standing ovation to, but nothing that left me feeling ripped off.
