Full Moon's catalogue of DTV horrors may be packed with guilty pleasures, but these initial entries in the company's 1990s vampire franchise are genuinely effective fright-flicks. Sadly, Subspecies' AVC encode is soft throughout, but things improve significantly with the sequel's sharp and detailed 1080p visuals (it also gets a 5.1 audio upgrade, unlike the first film). A handful of extras are shared across both discs, but they do get their own commentaries and archival Videozone promo featurettes.
