Well, this thing really crept up on me.
But over at AIPT I have my review of TMNT Half-Shell Heroes: Blast to the Past, an original one-hour TV special.
It's aimed at younger kids, but the 2-D animation provided by Titmouse is actually really good and the comedy is pretty spot-on. Mostly physical humor, but that's where the lively animation helps.
Also, lots of Bebop & Rocksteady, if that's your thing.
