IDW's Teenage Mutant Ninja Turtles series hits a big milestone with this issue. And the occasion certainly feels momentous, as issue #50 effectively caps off the past four years' worth of storytelling while simultaneously paving the way for new things. Even though the cover price is fairly high (despite the extra pages) and one of the key elements in this issue falls a bit flat, the overall package is satisfying. Issue #49 set the stage for the final showdown between the Turtles and the Foot Clan, as our four heroes face off with Shredder's mutants in hopes of challenging the top dog himself.
