In fact, I just watched Avengers Age of Ultron and this movie back to back and I enjoyed this more. Given I've seen a lot of superhero movies so Avengers style movies were getting a little old to me and plotwise a dime a dozen. For effects and action, Age of Ultron did not disappoint in that arena. What We Do In The Shadows is a completely different movie though from Age of Ultron in every aspect so it's not fair to compare the two other than that I saw both and enjoyed this one more.
Short of spoiling everything, I can't think of too much to say about this movie other than how great this is. It's refreshing, different and a take on a genre that has been overused for certain.
Now, if you're up for SPOILERS to get a taste of what this movie is about, read on...
Fair warning that this movie will be a lot more enjoyable for 3 types of people: those who somewhat enjoy vampire movies, enjoyed but are now sick of vampire movies or know the general vampire movie elements. It's a hilarious take on vampires lifestyle in a mockumentary. There was a few parts where it leaves the viewer wondering, ok, now what, where could they possibly go with this story and it's going to be the same thing I see in all vampire movies? It did not disappoint, it introduces familiar elements of vampire stories in very unexpected ways and does this with humor no less. It's been a really long time since I've seen a movie this original and I absolutely loved it!
