I'd like to start off by saying I'm a big fan of this movie - mainly for the nostalgia factor (it was the very first film I saw all alone in a movie theater, as a young boy). Nevertheless, I'm not blind to its deficiencies. As a movie, it surely doesn't hold up all that well, but as a fun collection of skits, it's quite alright.
The BD doesn't seem to have any remastered bits, as the image isn't all that different from the DVD. Nevertheless, the increased resolution works wonders. The sound is quite nice, featuring a completely acceptable mix. The extras department, however, is surely lacking.
In sum, if you simply want to have this in the highest quality yet, you're in luck. If you're looking for anything else, feel free to move right along.
