My grandson loved the Transformers movies even though I can't remember a thing about the first one (the only one I've seen). Lindsay Ellis did an essay on why the first one is so forgetable (hint, its Michael Bay's direction). I also was way too creeped out by the decepticon woman (Alice from Revenge of the Fallen) which was a total Michael Bay creation showing a bit too much about Bay's issues with women.

Avatar has James Cameron's solid direction and scriptwriting. It has the kind of strong women that Cameron can seem to write that others cannot seem to get right. But Avatar gets into some creepy themes much the way True Lies did to which Cameron clearly has a blind spot.
