They are back with even more stimulated to fight the crime. Another great addition to the franchise, I completely enjoyed. The first thing is the pace, it was so fast, from opening to the end, non-stop actions and comedies. I regret that I was not able to watch this in digital 3D, other than that, this is a wonderful film for TMNT fans. I know, some people downgrading it, but don't believe them, it is just a fine film if not an awesome as I'm praising, particularly keeping in my mind the common people. So watch this for entertainment and it will deliver for sure. There are some flaws, but I did not care about them, because it was not a documentary film or even a sci-fi film, it's just a fun-action film. So everything was aimed to bring laughs and it did successfully. If you go with science, then this is a nonsense film. Anyway, the vfx was very impressive, the CGI characters looked even better than the previous one. Don't compare it with the DC or Marvel's films, it is setting up its own trend. Like those new additions, Rhino and Warthog characters were seems more like reading a comic book, straight outta from the sketches. Excellent follow-up and expecting another sequel in the next two years. The director of 'Earth to Echo' did a great job, and also all the actors. Little disappointed was the villain. I expected some strong confrontation between the heroes and the bad guys which was a let down. Though, all the stunt sequences were well designed. Those clichés like a mad scientist, alien invasion, hole in the sky et cetera, did not stop me from having a good time. Surely I would watch it one more time, just for entertainment, that's what this film is good at. I suggest you as well to watch it if you're seeking the same. 8/10
