I had fun with 'Slasher House'. By no means a perfect film, it's an enjoyable British mashup of various slasher tropes and homages. The budget is clearly low, but you can tell the director's passionate and is determined to make the best with what he has. The film looks really good for what it is. The green and red lighting and colour pallette seen in other slasher flicks like 'Saw' and 'The Collector' adds a really visceral feel to the dilapidated blood-soaked walls. They succeeded in building an unsettling atmosphere with their cinematography and setting. I love the look of our leading lady too. Her bright red hair, lipstick and dress really help to distinguish her from other female slasher protagonists and give her a memorable look.
The gore and make-up effects prove well-done and there's enough camera trickery and skill to hide any low budget flaws without resorting to shaky-cam.
The overall idea of the film is very fun: a amnesiac girl trapped in a place full of violent serial killers. Right there, is how you build immediate tension and all our killers did a fantastic job of bringing a real sense of peril to the situation.
The film falls a little short for me around the third act, becoming too focused on flashback sequences used for exposition. They lasted too long and somewhat hurt the pace of the film. I feel like the better option would have been to use the flashback sequences sparingly over the course of the entire film rather than squeezing them all in towards the end.
There's also some romance that feels rather out-of-place. You could argue it becomes necessary in the third act, but I don't think it was - the same thing could have happened without romance needing to be involved.
Overall, if you're a slasher fan or like shoe-string budget films, I'd recommend you check this one out. Again, it's not perfect, but it is a fun nod to the genre and I think you'll appreciate it - just keep in mind that it's very low budget and the cameras used and special effects are not million-dollar-movie style. However, if you're not a slasher fan, this one will probably not be for you - it's clearly made by fans, for fans.
