Mean spirited contemporary UK horror effort
27 May 2011 | by (the Doomed Megalopolis of Blasphemous Technoids) – See all my reviews

"LD 50 Lethal Dose" was a nice surprise, and actually a lot better than the trailer suggests (which, thankfully, I saw after the movie, on the "special features" menu). Scary Spice was actually pretty unrecognisable in the movie. At least, to me she was. Never really kept track of the Spice Girls, anyway. All the acting was pretty okay, even. All I can say is, if you like recent British horror, like "Dog Soldiers" (2002), "The Descent" (2005), "The Hole" (2001) and "Long Time Dead" (2002), then you'll most likely enjoy "LD 50 Lethal Dose" also. Its not on par with the first two I mentioned, but it can compete with the last two. It did take me a bit to get into it. It knows a very standard set-up (first half hour), but in the end the movie is saved by a pretty original concept (even though "LD 50" deceivingly starts as one of those 'a group of people on an isolated location are about to be killed of by some killer-something' type of movie), good cinematography (look & feel) and set design, very decent special effects and blood & gore make-up effects (well-timed, rather than a non-stop display), okay over-all acting, and a satisfying finale/conclusion. Just keep one eye closed for some implausibilities in the script and don't try to think too much during the movie, and you'll be okay. First time director Simon De Selva left a good impression on me with "LD 50".
