Yes, this movie isn't that awful. It does have some questionable physics, and a whole bunch of plot holes. It even has some bad actors! But in the end, it keeps going well enough to maintain interest, albeit sometimes only to see what foolishness comes up next.
The main star (I guess) is Greg Evigan, of BJ and the Bear fame. He doesn't have a chimp side-kick here, though. In fact, there are a whole bunch of people who filmgoers will recognise, if not be able to put a name to. But the real star is Miguel Ferrer, who has a kind of Hudson-from-Aliens role. He gets increasingly manic as the film progresses until he finally loses it totally. The movie is worth watching for him alone!
The plot is the usual "science tampering with nature" deal and the ensuing onslaught of nature on science. Nothing remarkable. Nothing that isn't predictable. The creature, however, is refreshingly different and done well enough with the effects of the day to not look pathetic in this age of CGI.
As I mentioned, there are some dodgy plot holes and physics, but the movie entertains enough that you can overlook them (for the most part) and just enjoy it.
All in all a film worth a look in on a quiet day.
