This movie was really fun to sit down and watch, and would recommend it to fans of either shows.
However, despite enjoying myself, this movie does have flaws worth noting. The humor was hit-or-miss, and when it missed, was thoroughly cringe-worthy. The original Teen Titans' humor seemed more in-line with their Go counterparts. Speaking of the originals, their character designs and color palates were slightly off, though I do understand it's been 13 years since its cancellation, and it's likely different animators are working on this movie (haven't checked IMDb yet, so I don't know for sure). Their personalities were also a bit off, especially OG Robin. Maybe this was done intentionally, maybe to reflect how the TTG versions viewed the originals, but as a big fan of the OG cartoon, this was off-putting, and I would be lying if I said I liked this change even a little bit.
I do understand this was ultimately a TTG movie, but the originals seemed closer to their Go incarnations than the characters they were in the original show.
I've heard the rumors that if this movie does well, the original will get a sixth season. I hope this happens, though if they act like they did in this movie rather than the 2003 cartoon, I can't say I would enjoy it.
As someone who can't stand TTG, I do not hate it, and the Go versions were tolerable in this movie.
Criticism aside, this movie is fun, and I do recommend for both fanbases, though Go fans may enjoy it more, and OG fans may have some problems with this movie, likely the same ones I did.
7.5/10
