I appreciate the third movie more after reading the comics. The time scepter of course was there, but the overall concept was something you could have seen in one of the first volume issues. However, the execution of the idea was bad. I really never cared for Corey Feldman as Donatello and thought the guy in the second movie was better, there was also the bad new Splinter voice, the costumes seemed worse and the new characters just weren't appealing. It was nice to see Casey Jones back, but even he couldn't save it.
TMNT was okay. The relationship between the Turtles was good, especially the confrontation between Raph and Leo. Everything else just seemed average. I didn't really like the human character designs, something about them seemed too angular.
