I like this crossover overall, but the execution was wanting. The 80s turtles are reduced to cowardly, incompetent, childish fools, with their individual quirks and personalities stripped away. (As silly as the 87 cartoon was, the green team was certainly not comprised of "four Mikeys" as 2003 Raphael suggests). It's really aggravating. 80s Shredder and Krang are given little to do and what little seriousness they had on the original cartoon is taken away. They serve as idiotic foils for the newer villains and little else. They weren't integrated into the plot that well either. The only 87 characters given the proper treatment at all were Bebop, Rocksteady, and Splinter.
It was cool to see the Mirage turtles included (and how they knocked down the 2003 turtles a few pegs). The plot itself was interesting, and the comedy and action generally worked well. It's just hard to praise this one when one half of its crossover is so shamefully treated. Honestly, it felt more like a "hey look at how cool the 2003 turtles are!" most of the time, rather than a celebration of the franchise as a whole. It's unfortunate.
