This isn't a bad film, or in any way an amazing one,
but it is a film with heart. The passion in the directing and script is very clear, and the acting is fantastic. As a solid Jack Black fan (saw Tenacious D live in Birmingham, UK), i was extremely excited about this film.
It looked like it had great comedic potential, remaking old movies - however, this seems to have very little to do with the narrative.
Sure, the entire premise is about two guys remaking films to save a business, but the real narrative is about a jazz musician who they want to celebrate in their final film.
It's touching, albeit a little dull - but provides some great comedy moments (try and watch the 'Driving Miss Daisy' remake without laughing).
I would say this is a rent, or watch it on tv if you can wait a while. If you love extras and such, then im sure you will like the dvd. It features a lengthy 'making of' which is good for a die hard Gondry fan.
