Would recommend to a fan of the franchise... for closure. As a fan of Underworld from it's first release, I'm disappointed in Blood Wars for being the only film of the franchise that I didn't enjoy. While it was visually beautiful, with promising characters and story lines, my biggest peeve is that the entirety of the film felt either rushed, or unfinished (potentially both). I was really excited whenever a new character was introduced, however, none were explored enough to justify their place in the film. This is frustrating because it seems obvious that the characters were thought-out well, given unique identities and backstories, however, the film failed to produce these. Our main antagonist, for example, is difficult to empathize in, and becomes more of a mere pest than the fearful, intriguing villain we've seen in former films. Same issue with most of the story lines, which felt too-condensed (was it a budget issue?) that you almost question their relevancy in the film, and if the film would have been better without them.
Blood Wars overall had so much potential to be one of the best films of the franchise, however, it was crammed with too many overlapping story lines into this 90 minutes of poorly executed 'movie', hardly explored in-depth enough to do them any justice. This easily could have been resolved if the movie had have been longer, or spread across two films. Hopefully the final installment will tie in what we didn't see in Blood Wars, and give fans (old and new) some closure, because Blood Wars will leave you asking "that's it?"
