It does sound a bit weird. Your instincts serve you well.

Hollywood doesn't make many movies like that, or at least good movies like that. So warm-fuzzy movies are usually labeled "sappy", "saccharine", or "chick flick". If it's pretty good, you might call it "sweet" or "feel-good".

I guess, "feel-good movie" is the best I can come up with.
