Just watched this with my partner. I had seen the early films in the Underworld series but lost track around the 3rd or 4th one. My partner had never seen any of them so watched this as a stand alone. We were both very entertained throughout. Great acting all round, stunning visual effects, nice leads and twists along the way within the story line. Would highly recommend this to anyone that likes the vampire/werewolf genre. Don't understand why this wasn't received better? We want more!!
