Ending!!
Please read this spoiler, it may make you think 'there's no point watching it now, dirge spoilt the ending' this is a good thing, tbh you'd thank me for it.
Wow, just WOW. I loved the way after they ran out of the manhole and a small fart of fire came out after them. They turn to each other, spout line after line of sloppy plot fixes.
It seems that after watching hundreds of scifi/horror/alien films they don't realise that.... always one survives for that possible sequel! nope they are just quite happy to resign to the fact that nade/suicide totally fixed the job. No need to go down and check, nope! no need to go down get an alien head to take to the press. ah sorry the governemnt coverup line took care of that one.
So glad it did end so badly and that it didn't pan to a surviving alien thing which could start all that crap again... a sequal just isn't needed.
