Predictability
credible constructed plot elements (to drama, plot ahead)
repetitive action (crew member leaves the rest of greed sit)
That makes the already not really original act only moderately bearable.
Add to this the one who is here an adventure film alá treasure of the Knights Templar also expects disappointed because in the 2nd half of the film slips the whole rather then in a B-movie monster from.
So not necessarily the hammer but on Viking setting leaves and with the above points not at war is like me, can give the happy times to nem nice evening :)
