Awful. Two main problems (a) an awful ensemble acting job, led by hey dude Paul Walker, and (b) completely unbelievable depiction of the medieval period.
For (a) - there's all these talented actors running around in medieval gear going "hey hey hey" as if they've improvised. Walker plays it completely surfer dude, not that interested going back in time just looking for his dad.
For (b) the middle ages just look like... a theme park. And we're meant to go for the French? I'm sure the French did.
Michael Sheen camps it up. Frances O'Connor goes down with the ship, as does everyone really except maybe Lambert Wilson. Billy Connolly seems absurd. So does Ethan Embry. Could they have not found a French actor to play Anna Friel's part?
Awful.
