I'm pleased that after seven seasons, the writers have not made the shredder any easier to take down, something that often happens with long-running programs. He whips the Turtles just as badly as he did back in 2003. Also pleasing is that despite this being a cyber world, the Turtles still have to fight hand-to-hand - their weapons don't release energy pulses or any of that silly Fast Forward stuff.
Pretty straightforward "toy-etic" episode, and I do agree I'd rather see more NY stuff than cyberspace, or at least a more gradual blending of the two.
