Terrible acting, screenplay and direction.

Absolutely the worst movie.

Amazing worth wacthing. So good. Biased but well made with many good points.

It's a movie as timely as it is provocative and amazingly, for much of its running time, it is weirdly funny.

Miranda (Helena Mattsson) is an university professor. She lives with her only family, uncle Tom Hollander (Ben Cross). Miranda is found unconscious and naked in the park. She is taken to the hospital where she transforms into an alien hybrid and kills several people. Tom arrives to find Miranda unconscious and goes on the run with her. He reveals the truth of her origins. They travel to Mexico in search of his former research partner Forbes McGuire (Dominic Keating) who helped create Miranda from combining human and alien DNA.This is the fourth movie of the franchise and a TV B-movie at heart. The horror and thriller aspect is only a shadow of the original. Mattsson is statuesque with sufficient acting skills. Ben Cross can't do much with this material. There seems to be alien DNA everywhere which devalues Miranda's singular potential for danger. There are long stretches where the film flatlines. This is not that good even considering its limited aspirations.

A college professor has been raising an alien/human hybrid he created as his niece. She starts to turn alien and then the Professor must take her to Mexico to find an old colleague who can maybe save here life.From then on it's just boobs, sex, killer tongues, and more boobs with some pretty dull action scenes thrown in between. It didn't seem to have much of a story.Straight-to-video movies are never that good and this was no exception. The lighting was bad and it was primarily shot in Mexico I guess to save money. The action scenes were not exciting at all. I was really disappointed. Doubt I will ever watch this again.

Realizing that his bio-engineered daughter is turning into her fully-alien counterpart, a doctor takes her to Mexico for help in controlling the change, only instead unleashing a far more vicious side to her than he imagined.A lot more enjoyable than imagined, due mainly to the fact that the warring nature of her transformation is almost always present, resulting in the changes that force out more action and science fiction elements as well as the occasional jolt of horror with some bloody killings spread throughout that give off some good points every so often. Again with the added element of a lot of extra nudity, a far more ferocious pace and some minor bioengineering babble thrown into the mix, this one comes out far better than expected and actually has some fun, especially once the rebirth takes place and there's actually a confrontation between two alien mutations that is a lot of fun in a cheesy manner. Has a few minor issues to deal with, but surprisingly nothing too serious as this is a lot of fun.Rated R: Full Nudity, Graphic Violence, Graphic Language and several Sex Scenes

Just saw the entire Species collection over two days, and i was very disappointed over the fourth in the line.After watching the first 15 minutes i sat the player to double time, and i sure didn't regret it. This movie doesn't have anything to offer, beside nude chicks and brainless "horror". Compared to the three other species movies, this is fare worst. If you have seen the movie "From Dusk Till Dawn" you sure don't need to see this one.Lets all hope the line will end here.blah. blah.blah.
