There's only one legitimate place I've found to watch it, the rest seem like scams :-/ You can see it over here though: www.watchfreemovies-online.com/streaming/watch82771.html Great quality btw !
try youronlydevice.com. you can even download movies from there. they re-direct you to other sites if you only need to WATCH the movie. you can check from the 20 or so links they have provided. hope...
If you're looking for the third movie, try transformersmovie.com. It's virus free, and lets you stream the movie for free. no membership and payment required.
