Scooby Doo 2: Monsters Unleased (2004)

I wasn't crazy about either of em but I would say the sequel is a little better.

To be honest, neither this or the first did much for me, even in my youth. Matthew Lillard is great, and Linda Cardellini does as well of a job as she can with the material as Velma, but both Prinze and Geller are essentially playing parodies of themselves and the portrayals of their characters as written are not very likeable to make me want to invest my time in them. The humor I have never particularly found to be either clever or very funny for that matter. It is pretty wild to think that direct-to-video offerings like Zombie Island and The Witch's Ghost touched base on similar things that these live-action offerings attempted to do (i.e. reuniting the group and encountering authentic supernatural threats) and handled them pretty maturely all the while respecting what had come before.
