A mixture of Alien and Ghost Busters?

Starts very promising, then slows down to almost boring.

LifeForce contains some awesome special effects they were able to make in the mid 80's. The story is intriguing, but becomes quite lack lustre in the end. It was rated R because of the nudeness, sex and gore. Mathilda May's ethereal and savage (naked) beauty is very apparent through out the whole movie. A bizarre movie and cost a lot by the time it was made.

This could have been a bigger classic with a better script, but unfortunately it wasn't a great hit, I think it actually flopped quite bad.

So, something went wrong with this one, but still, it's very entertaining.
