The cover of this DVD had me worried, but the episodes ARE the original 5 (and then 3 of the later ones that make you realise why the series was cancelled). The bonus episodes were a little odd, and the DVD put the first 2 in the wrong order. My friend and I didn't understand the first one at all, and then we realised it should have been second.
But overall, this was worth the money just to see those first 5 episodes, I had never seen the first ones as a kid. It was also funny to realise that James Avery (Uncle Phil from Fresh Prince of Bel Air) is the voice of Shredder.
