TMNT is unique, in that the revivals didn't screw everything up. I've hated most the Transformers revival cartoons and don't even acknowledge the existence of the Michael Bay movies. TMNT 2003 and the 2007 film I thought were astonishingly good.
Live action series.
I said it.
There are a lot of blotches on the TMNT's record, most of them just side marketing things from the old series... that horrible first video game, really stupid easy reader books, those terrible, terrible concert videos (though Pizza Power is a pretty enjoyable song). But the live action series, which if Shout releases, I'll give a second look into... but the live action series ruined all its potential because of the network and really, really stupid decisions made about a much better second season that didn't exist.
I only need to say Venus. Now the thought of a female Turtle was considered Pre-fan fiction by girls ticked off that there wasn't a fifth member that was female, like them. The show quickly proved why they were wrong. No one wants a fifth Turtle anymore than a fourth Stooge or Laurel, Hardy and some other guy. The fact that she was personality devoid only added to the mess. She was added ONLY for the completely hypocritical reasoning that all boys shows have to have positive female role models when girls cartoons mostly
- have nothing or need nothing to appeal to boys
- have bimbos or otherwise vapid characters anyway.
The problem is, April O'Neil (the positive female role model in every TMNT version there is... though, frankly a better one in 2k3) didn't come in till the second season, which never got produced because the show was shockingly a hit, but not so much of a hit that it justified the high budget.
There are a lot of wonky episodes in both 87 and 2k3 (especially the last season with Lord Dregg and the seasons where the toy company screwed them around respectively), but nothing as bad as adding a female turtle with no personality to screw up the dynamic.
Even then, the live action one cost the turtles 7 years.
