I very much liked this film. Realise it's not a big production and perhaps amateurish but it kept me gripped. I like the build up and the tense atmosphere. The ability for the viewer to have their take on what's going on was good. Some bits are odd,, like the when he is speaking with a British accent although he is an alien that has landed on the British Isles for the first time. The anger against the dead corpse reminded me of the scene at the end of planet of the apes when Heston throws a wobbly.
Overall, I did get to the end. Most of the time I switch off through half way through a film, especially major Hollywood films. I suppose it's not everyone's cup of tea but it was mine.
