Why is summer not backing up down the corridor? taking off arms one by one as she covers their retreat? I mean if the wolf is intelligent enough to know it is about to sacrifice its own life, wouldn't it try and create the best defensive odds? Isn't that just instinctual for a creature that has been raping the countryside as an apex predator taking out pack animals?
The fucking skeletons climbing the wall and ceiling of the tunnel was fucking overkill. You don't need to do that, its superfluous hollywood CGI shit that didn't need to be there. The dead crawling over all over the tunnel did not make the scene more intense, it detracted from it.
The only way they make it out is if the Dragon comes and it roasts everything and carries them off.
