Thus spoken by Forbes, who explains how he may be able to reverse the problem that Miranda has. Forbes and Tom collaborated in alien-human DNA experiments, and Miranda was one of the better results. But she starts to show her alien side, and Tom takes her to Mexico to catch up with Forbes to see if there is a cure. Turns out she is dying of old age, and needs a genetic transplant to reverse the process. Of course, as Forbes explains about the process, there is always one or two glitches. The last 1/3 of the movie goes, one might say, to the dark side, and gives the viewers what they expect from the Species movies. Unfortunately, the movie seems a bit tired compared to prior ones in the series, and Tom seems to be stuck in a serious case of delusions about who Miranda really is. Only Miranda really seems to understand the situation. I can see where they left the possibility of still another sequel, but it doesn’t seem necessary.
