Favorite Scooby Doo Movie/TV Special/Direct to Video Special

[InformationGeek]

I just took a look a while back and wow, there's a lot of movies.  No seriously, there are 26 movies based on the dog, most of which are direct to video or TV specials, but still.  Having grown up on Scooby Doo and seeing a bunch of those films, I've felt a bit nostalgic recently.

So, why not talk about it?  What is your favorite Scooby Doo film?  My personal favorite is Scooby Doo Meets the Boo Brothers, with Zombie Island and second live action following close behind.  I liked the mystery in it, all the possible suspects, all the strange happenings going on in the movie, and I really liked the animation in it.  It was creepy and sort of atmospheric a way.  You opinion may vary on the comedy and of course Scrappy being in it, but I loved it as a kid.  In fact, I may want to see it again at some point.

There's a few that stick out to me above and beyond the rest. 

Scooby Doo and the Reluctant Werewolf is cool because it brings out all those classic monsters, and I'm a sucker for classic monster gatherings, plus it has a catchy song.  I do find it kinda odd that this is the ONLY appearance of Shaggy's girlfriend in any version of the show or movies. 

Scooby Doo on Zombie Island was a nice update to the cast and considerably darker than most of the previous ones. 

The second Live action was also great.
