The first time the alien appeared I was in shock just how awful the CGI was - more Dire Effects than Special Effects. It was almost funny - I had to get the wife to check I wasn't just imagining things. The alien design was bad, the implementation bad - that I can only think they ran out of money in post-production and made the wrong decision to release. It really looks like they've given it to some teenage kids who don't really know what they're doing. The fake blood is bad, the integration with the performers and set is bad. As the alien runs forward it's head shuffles oddly - as though it was added on separately after the body action was done. The action was awful and the acting poor. The director has cooked up a turkey - the very worst film I've seen for a long time. I'm stunned that can get released as a movie and show on terrestrial TV in the UK.
