I do like Riddick but this felt like a training montage with gratuitous nakedness (really, that scene needed her naked?) and much violence. It was somewhat science fiction but could easily have been fantasy.

Riddick is betrayed and left for dead on a planet where he finds a depot with an emergency button. There's still a bounty on him (doubled if he's dead) and when two teams of mercenaries turn up they both have agendas and he will have to battle to get off this planet.

I felt that sometimes it went on too long and a serious edit would have helped. I was also annoyed about the comment during the extras by Katee Sackhoff that she thought her costume wasn't sexy enough and wanted it changed. I would have wanted more armour around Riddick. ( )

Vin Diesel gives an excellent performance as Riddick. Special effects are first rate. Not as good as the first two Riddick movies. Overused the F word. Very violent movie. ( )
