Well done! The franchise recovered after the fourth and fifth movie (quite plain imo)
it has some interesting twists
though when the credits started, I was like "WTF?! I thought this one was going to be the last!" but as I've heard, they are going to release two more movies, and probably the seventh one is going to be on 3-D.
But well, nothing official I guess.
(it's just me or are they expanding the franchise until the actor who player Dr. Gordon accepts to appear?)
