It's refreshing to have a faithful adaption of TMNT after all the shenanigans of the 1987 show. Sadly, 4Kids is attached so the series feels restricted to the younger demographic. Shame because the 2003 series starts off really strong and is a faithful and expanded adaption of the original Mirage series from the 80's. Sadly because of the censorship 4Kids is known for, what suppose to be an edgier more action orientated series comes across as cringe more often than not.
Turtles have their initial battle with Shredder, find out Splinter has gone missing, get taken to the Triceriton homeworld and participate in the Battle Nexus and have to deal with a full scale Triceriton invasion of Earth, fight the Shredder again, etc. Seeing the original stories adapted is pretty cool.
I can't recommend watching the Fast Forward and Back to the Sewers seasons as they're just nonsense and don't provide much in terms of entertainment.
