When first discovering the podcast, I did pass on any film I really had no interest in watching. Especially those that you really have to see unspoiled to get the full effect. Once I was caught up, however, I eventually went back and just watched them with the commentary and said screw giving the film a chance

About the only time I had reservations about listening to the commentary of a film I liked was Avatar, but that didn't stop me from giving it that first listen.

I think I've listened to pretty much them all (incl a few live ones after finally working out the English / USA time conversion thingie), but one commentary I won't be listening to is UHF (that recent Wild Al thing). Not cos I don't want my view of the film shattered by the panel, but because the trailer has one of the kids spitting on the star. While I have no problem with graphic violence and foul language (rock on), the whole phlegm(?) in the face thing really grosses me out, and thus turn me off from watching the movie. Although iirc both Planet Terror and Showgirls having such scenes and I'd watch those again, so i guess I just one big o'hyprocrite.(?) 

I have yet to listen to the Mulholland Drive commentary as I have no desire to see the film. I have seen the lesbian scene, that's enough
