Loved this film when it first came out. Not so sure it still stands up now but back then there was so much to like about it. In fact it's biggest problem is that there's almost too much going on and being told too quickly. It feels like it would make a far better TV mini series. A modern day Quatermass with blood and boobs and the walking dead! Neale would turn in his grave of course but it would be a definite crowd-pleaser.
