I'll give Fox credit for one thing -- at least she does see herself as an actress and does try to act. I'm not saying that she succeeds terribly well, but she does view acting as her career. This is different from say Rosie Huntington Whiteley who's primary career is modelling, and her acting stint was just something on the side. RHW's "acting" makes Fox look good.

As for the trailer, I'll admit it does look fantastic. But we all know that Bay is really good at creating beautiful trailers that suck audiences into cinemas and pump heaps of money... but it doesn't necessarily mean the films are any good. One of my Year 8 students today referred to the Transformers films as the highest grossing bad movies of all time. I'm not necessarily saying that TMNT will be good or bad... but it's hard to judge a Bay film by its trailer.

IMO the look of the Turtles themselves remind me of the 1989 computer game (especially the Famicom/NES version) with the longer legs and rounder shells.
