You can't expect much from a direct-to-video, CGI, Lego movie. And it seems almost appalling that Warner bros. would allow a film like this to be made or that someone would even conjure up the idea for this movie in the first place.
But surprisingly enough, I didn't hate it. I mean don't get me wrong, it's not a good movie, but its not nearly as bad as the premise led me to believe.
First of all, they did manage to get the official voice cast together to make this. That alone improves the film. The movie also has a pretty classic Scooby-Doo plot that is executed fairly well. On top of that, they managed to pull off the comedy. The jokes were good and they even had some pretty clever Lego-inspired gags throughout.
But of course, this movie does fall short in a lot of areas. Besides the funny bits, the script was poorly written. The supporting characters were throw-away consisting of an unsettling and unappealing tour guide, an off-brand Elvira, and not one, but two generic J Jonah Jameson ripoffs.
The ending was also completely predictable, they didn't give Velma anything to do throughout the film, and they mis-characterized Daphne by giving her a craving for fame. A trait I don't recall from any of the other movies/TV shows.
In the end, this movie obviously isn't great, but also isn't a train-wreck and I'm sure your kid will love it if they like Scooby-Doo and have a weird thing for Legos.
