Lifeforce (1985)

Lifeforce is a 1985 British science fiction horror film directed by Tobe Hooper and written by Dan O'Bannon and Don Jakoby, based on Colin Wilson's 1976 novel The Space Vampires. Featuring Steve Railsback, Peter Firth, Frank Finlay, Mathilda May, and Patrick Stewart, the film portrays the events that unfold after a trio of humanoids in a state of suspended animation are brought to Earth after being discovered in the hold of an alien space ship by the crew of a European space shuttle.

On release, the film received negative reviews from American critics. Janet Maslin of The New York Times wrote, "[I]ts style is shrill and fragmented enough to turn Lifeforce into hysterical vampire porn." Michael Wilmington in the Los Angeles Times said the film was "such a peculiar movie that it's difficult to get a handle on it." Jay Carr wrote in The Boston Globe that "it plays like a tap-dancing zombie." John Clute dismissed Lifeforce as a "deeply silly flick". Leonard Maltin called the film "completely crazy" and said it was "ridiculous, but so bizarre, it's fascinating."

On the other hand, science-fiction film authority C. J Henderson praised the film: “Lifeforce is an incredible film, and may by be the most intelligent vampire movie ever made ... [The ideas presented in Lifeforce] are beyond [others vampire movies] beyond all of them, light-years beyond ... the story is what makes this movie hum.... Lifeforce is a true, thinking sci-fi fan's film." Andrew Migliore and John Strysik in their Lurker in the Lobby explain that Colin Wilson wrote The Space Vampires as a consequence of H.P. Lovecraft's publisher August Derleth challenging Wilson (who was critical of Lovecraft's writing) to write a Lovecraftian novel himself (a challenge that resulted in three such novels, The Mind Parasites, The Space Vampires, and The Philosopher's Stone), and they continue, "[Lifeforce] is big, splashy, and ... the scenes of an apocalyptic London are not to be missed. And the film, an obvious tribute to Nigel Kneale's Quatermass, has deep roots in Lovecraft's mythos." Film critic Gene Siskel of Siskel & Ebert called the film a "guilty-pleasure", awarding it 3 out of 4 stars.

Personally, I don't know why, but I adore this film. It's a weird beast for sure... a twisted bastard child of many illustrious fathers. At moments blindingly brilliant, just to go completely deep shlock in a second. In that respect it may be the film with the closest "feel" to what Lovecraft is all about that I've ever seen.
