Well, the Amigos enjoyed it well enough.
As for me, I wasn’t really into it. Without trying to spoil too much, April’s involvement in the turtles and Splinter’s origin is a poor attempt at linking them together, the CGI isn’t that good looking, and the Foot Clan aren’t even ninjas, just thugs with ARs and crappy masks.
Splinter learned Ninjitsu from a manual he found thrown away in the sewer, which he mastered and later taught to the turtles. He also somehow managed to obtain quality, authentic “ninja weapons” for them to use. My belief was suspended at that point (because talking turtles who also happen to be ninjas is a totally believable premise, right?).
The positives? The action scenes aren’t that bad, and I chuckled a few times at the admittedly lame jokes. It’s ok for the kids, but TMNT fans won’t find anything worth watching.
If you need a Turtle fix, go watch the 90s trilogy; even Turtles III is better.
Verdict: Wait for the home release, if at all.
