being more fair
my actual opinion is that there's about an equal amount of faults in both classic TT and TTG!
TT's faults were
1. its shameless attempt at being "anime-like" and failure to do so well
2. it's mean spirited humor (which is also Present in Go!) almost all of which directed at Beast boy
3. it's inability to keep Beast Boy's vegetatianism consistant, and on some level, the decision to even make him a vegetarian in the first place (he was not one in the comics)
4. not balancing humor an action well at all, the show flopped back and forth between being dead serious and dark (Raven is the Anti-Christ her father is Satan and the earth is now hell), and "LOL SO RANDUM!!!111" comedy (Beast boy fighting talking space Tofu who wants to use cows as batteries)
and TTG!'s faults are
1. abandonning action entirely in favor of LOL SO RANDUM comedy (though I occasionally laugh at some of the jokes admittedly)
2. Family guy esque Political soapboxing (albiet on a much milder scale cause it's a kid's show), and
3. regularly insulting both it's fans and it's haters
