Yes, they look absolutely ridiculous, but bear in mind the Teenage Mutant Ninja Turtles actors are wearing Motion-Capture Suits.
We've already heard that their looks is being compared to Avatar, and this isn't the first time we've seen suits such as these.
Michael Shannon wore one for Man of Steel as well as the alien Chitauri army in The Avengers - and those turned out pretty good.
Looks like the Turtles get captured as they appear to be hand-cuffed.
