I had a nice Super Mutant kill where they did exactly what you would expect. I shot the mutant in the chest and he died, turned halfway around and slumped over a banister. Kind of nice.
This is of course balanced by the ridiculous deaths like the anti-gravity critical.
My favorite so far is getting kicked by the skeletons that litter every cave, tunnel, sewer, hole in the ground, ditch, etc. I don't think they do any damage but listening to my character grunt because he got kicked by a skeleton makes me think of Army of Darkness.
Hail to the king, baby.
