It's better than Underworld Awakening in my opinion.

Its got much more going on than the Awakening plot, of all the sequels, its the closest in tone to the first movie.

I actually really enjoyed this. I felt like the plot was less muddy than the other Underworld movies. I really hope they make another one.

It's a no-brainer but good fun. I only ever watched the first two more than once, but I'd watch this one again sometime...

Better than Awakening. I think what impressed me was that it felt like it was doing some world-building with the new characters.

it's better than Awakening but not quite as good (or entertaining) as the first two

It's much better than Awakening, and I agree it's up there with the first two, 'Underworld' and 'Underworld - Evolution' and I hope they'll continue the franchise with the new characters and storyline.
