I loved the origional Teen Titans cartoon when it first came out and didn't care much for Teen Titans Go! until I started seeing all of the deep cut references snuck in to the episodes.
I laughed out loud several times during this movie.
The only thing I didn't like was the way Beast Boy's speach was turned up to 11 and similarly Starfire putting so many "the"'s in her sentences.
I know they spoke this way in the cartoon but never to this extent.
