Frankenweenie: The first half is pretty bland, but once it turns in to a monster film, it's great. The ending is kind of a letdown, but still, something I'd recommend watching if you like stop motion, and it looks great on Blu-Ray.
Frankenweenie (The original): This was the original short film that Tim Burton directed in the 80's, and it's live action, and has Jason Hervey and Daniel Stern from the Wonder Years in it. Take what I said about the animated films first half, and make it this full feature, just dull, something about it just seems rushed, and at the same time, boring. It's interesting watching this after the animated film, to see what changes were made for the better of the overall films between the two, such as how Sparky dies, for example. Not worth seeking out, but if you're watching the feature film, worth a look, at least.
