Having seen most of the films in the genre of "HPL inspired" from Hollywood to the HPL film festivals, I can honestly say that this film was one of the most enjoyable. It brought HPL to life in a believable, respectful and moving way (most of us who know HPL may recall that no motion picture nor audio tape of him is known to exist; only still photos and his writings, so this was something of a treat).
The few "monstrous" special effects were too hokey for this film, however and could have been either done better or left out and thus left to the imagination. Other than that, it was nice to see the mixture of name-dropping and time-interweaving done in the style of HPL's stories. That is, mysterious, suspenseful and ultimately pulling back the curtain to reveal cosmic horror behind it all.
Memorable moments: - HPL trying to sound out "Cthulhu" to himself - HPL's dignified manner of holding himself and his careful articulation - HPL describing the Nightgaunts which came to him in nightmares since he was 6 years old.
If you like HPL (not if you're a fan of the ultra-gruesome, not-in-the-style-of-HPL crap films like Re-animator and From Beyond) then you'll truly enjoy this movie.
