If you get noggin or nick jr, Franklin the Turtle and Little Bill are really sweet (and my husband and I like Little Bill too, a show by Bill Cosby, all positive about simple things like family, community, learning how to play together, etc). The whole family's favorite show is Jack's Big Music Show (sounds stupid, but it's a lot of fun and even we parents love it and have watched it when the kids weren't even present). You can buy the DVD online or at the store (unfortunately, just one DVD...there's also a CD we bought, heck, we even got the boys a "clubhouse" like Jack, and we're even having a Jack's Big Music Show birthday party in November).
As for movies...that's a hard one. If he's super sensitive then Disney may be out because I think there's ALWAYS a bad guy or a dead parent (usually a mom). Perhaps Cars, Charlotte's Web, Mary Poppins, Babe, Sound of Music, Chitty Chitty Bang Bang, that kind of thing? The 2 year old may not sit through the whole movie but music can bring their attention back.
