I thought X-Men Origins: Wolverine was godawful.
I liked the start, but it quickly went off the rails a bit and suffers the curse of prequels, finish with a fight between two guys where you know neither of them is going to die (see also Revenge of the Sith). Of course you could say the same about First Class yet somehow this seemed to avoid the issue, or was just so well made it didn't affect the quality of the film.
Ideally Die Hard needs a good solid action director, as has been said they don't need anyone oscar worthy, but they are in the upper strata of ation fims and the writer/director should be commensarate with that.
Still you never know. McG is a terrible director yet I loved Charlies Angels, and I always liked Bryan Singer until he turned in the turgid Superman flick so anything is possible.
