"Ultimate Showdown" serves up the last 12 episodes of TMNT's first season. It's a series that a lot of people wanted to hate (including me, since I grew up watching the 1987 animated series)...but fortunately, it's a ton of fun and probably the best TMNT series to date, even after just a few dozen episodes. The terrific action, humor, new characters and cinematic feel are easy standouts, as well as the voice acting and nods to the 1987 series. Unlike "Rise of the Turtles" and "Enter Shredder" (the first two Season One "volume" releases), this doubles the episode count on two discs for only about $5 more. I'd have given it five stars for the fun factor, but Nickelodeon's continued practice of avoiding season sets is just irritating. With any luck, we'll get a complete Season One release---and hopefully on Blu-ray---in the near future.
Other than that mild annoyance, "Ultimate Showdown" is unquestionably worth buying. These 12 episodes feel bigger in scope and execution than Season One's first half, answering plenty of questions without filling in all the blanks. If you're new to this 2012 series, start with "Rise of the Turtles" first...but if you're like me, it won't take you long to get caught up. The DVD itself looks and sounds good, presented in 16x9 widescreen with a terrific Dolby 5.1 audio track. Bonus features are minimal, but the series itself is the real selling point here.
