Any one that thinks this is terrible you are wrong it combines what made the original series and 2003 series great. Also season 2 is just as good as all other tmnt (except next mutation) series combined. I am loving what nickolodean is doing now with tmnt.

I grew up watching the 90s TMNT, and wasn't too sure at first about this new version. But as I watched it and realized how much they reference the 90s series, I loved it!
