This was a decent movie. It had good animation, funny jokes, callbacks to every Teen Titan franchise from the original comics to Teen Titans Go, and great fight scenes. However, it is still a Go! movie. The original Teen Titans lack the fun, unique personalities they had in the original show, but they still are fun to watch. The Go! Titans are fine, but they steal the spotlight way too much. If you're like me, then you prefer the original show for its clever writing, unique style, complex characters, and amazing chemistry, but you don't mind Teen Titans Go! I would recommend it, but if you find the Go! Titans insufferable, then you will hate this movie. I liked the BBRae fan service. Overall, it's a decent movie. I would watch it again.
However, as a Teen Titans fan, seeing this made me wonder if we should leave the original series alone before these characters star in the final season and end the whole series on a sour note.
