LMAO they should have retitled this episode "things don't change". Same turtles,except they look other and we have modestly better budget at our disposal than the original.
The turtles are attacked by robots than we recognized from the old series as being Krang's robots. Splinter apparently dies in a caving (which would have posed new possibilities) , but later is unexplicably found alive later\ on (saw that coming). The Turtles are attacked by a couple of punks called the Purples Dragons. Then they get a bit of a challenge from Foot Clan who we will recognize from the old series as belgoning to Shredder.
Ho-hum opener. Really they didn't change anything, so the title is very misleading. An ok opener but nothing special.
