I recently decided to rewatch all of the older Scooby Doo movies after being reminded of them from a podcast. The classic Zombie Island movie was fantastic, its animation, art design, voice acting, sound tract, defined the original movie and made me, someone who hasn't watched those movies in roughly 15 years want to rewatch them. This sequel was awful, when I decided to watch it, I was expecting the movie to build off the original, but all it does is take the concept and twist it into something else entirely. The plot was subpar, and the characters were degraded into idiots. Shaggy was the worst, for the first half of the movie, he forced the entire gang to not solve mysteries, which results in them walking into a scenario that is painfully similar to what happened in the first movie. This film also treats the gang as teenagers, which they are not. This movie retcons their age, making them a lot younger, in the original, they are older and have their own careers until they decide to bring the gang back together. The soundtrack was out of place don't expect anything close to Terror Time, and the voice actors for Shaggy and Velma were just out of place, Fred, Daphne, and Scooby were good though. The character designs were actually good, I liked how they were modern but were based off the old design. This whole movie was just silly, even if it was made for kids, I hate it when companies make mindless movies for kids. The original movie was made for kids, but good enough that an adult can still enjoy it, this movie was just frustrating to watch. If you have a kid, just watch the original movies, they aged very well and are much better than this.
