- After you learn that they're the good guys, any scene in which the Zombies attack the three cat-people count as this. Special props to the fact that most of the time, it's specifically done when Scooby and Shaggy were in trouble, such as when Simone and Lena had grabbed the two and were about to drain them of all life, the Confederate soldiers jump them. They literally have little-to-no chance of actually hurting the villains, but they still care enough to try and save others from their terrible fate.
- The flashback scene that opens the movie, not only for being a well done movie opener but also for being the first Scooby-Doo movie to actually make the gang's job exciting and even dangerous.
- There's also some genuinely great music to rock out to. Particularly of the Punk variety.
- The Ghost is Here is a great track for the montage while It's Terror Time is some great Horror Punk for the zombie chase scene. You absolutely cannot go through listening to them without getting sucked in & rocking out. Helps that they're EarWorms too that don't get old. In fact, they get better the more you listen to them.
Awesome / Scooby-Doo on Zombie Island
For as dark as the film is, there are some legitimate moments of awesome. Many come after The Reveal.
