Where this movie falls short ...
I couldn't agree more that Mumford is underrated. It's so good I've seen it three or four times. But I've been trying to figure out where it fails, and I think it's the sex/porn stuff.
Mumford is a charming, funny, quirky, small town romantic comedy with a great cast, with so much sexual content that it that --nearly-- sabotages the whole thing.
One big scene takes place in Skip's (Jason Lee's) secret lab, and many shots feature prominently displayed nude (fake) women. Which is fine, but it's not going to play on network television.
Dr. Follet's whole sex/fantasy problem is a little creepy, and the fact that Dr. Mumford helps him (and brings tears to his eyes) by giving him a box of old porn is a bit ridiculous. Pairing the unappealing Pruitt Taylor Vince with the beautiful Mary McDonnell doesn't help. For those who disagree or find this harsh, I admit I have a strong dislike for the overweight Mr. Vince -- if his "trademark" eye movement is a medical condition, so be it, but if it's an acting choice, it wore out its welcome long ago.
Then there's Doc's flashback story, with more brief but strong female nudity.
Ultimately so much nudity seems less to do with the story and more with the director's own obsessions. In fact, thinking back, it seems like two different movies. One remembers the warm performances, led by Loren Dean, but the other stuff is there, too.
