The Invitation manages to be a mediocre horror film that had plenty of good ideas ruined by a poorly thought out script, this is a film that definitely could have been more. The result here is a tiresome film that doesn't look like there was any effort into making something thoroughly engaging and thrilling. The tension here is never really present and the cast is pretty wooden in the way they approach their roles. The film could have been a fun, entertaining low budget horror film, unfortunately, it never takes off and it ends up being a tiresome affair that isn't worth investing your time in. I really wanted to enjoy the film, unfortunately, it didn't do anything to grab my attention or entertain me. I felt that there were some good ideas at work, but it never really materializes into something truly good, and I think it's a shame because The Invitation could have been quite the horror film. The cast is lead by famed cult actor Lance Henriksen, and he's really the only good thing about the film. He displays something interesting and engaging, but due to lacking ideas, Henriksen doesn't have much to work with and he does what he can with the so-so material. For those wanting an entertaining low budget horror film, look elsewhere, you won't find it here, as it leaves a lot to be desired in terms of what it could do. The film is dull and tedious, and there never is anything happening, which makes you wonder what the director was thinking. The film just wastes a good idea, and never does anything with its story to really entertain or thrill the viewer, and it ends up being a pointless picture that's not worth your time.
