Is this movie really necessary?

Rating: Null/10 (20 January 2004)

I will say this: it is fun to watch, and this is one of those late night movies that helps me sleep. The script is OK and the planning is rather poor. There are mistakes after mistakes. I'll point them out.
Spoilers ahead!!! Don't read unless you want to spoil the movie.
First mistake: the guards stationed outsite the lab have their weapons pointed at each other. Kinda funny actually.
Second: Riply is supposed to have some acid in her blood. The surgical instruments survive without a hitch.
Third: Checking Riply's health, the doctor uses a gionioscope (that is used to look at the corners of the cornea in the human eye). It looks kinda cool though, but do what Lucas does and dress it up a bit!
Fourth: The crew of the Betty comes aboard. Those screeners would be fired from any airport, yet a top secret military spaceship does not perform a more throurough search?
Fifth: "Jesus Johner, what did you put in this? Battery Acid?" "Just for color." Come on now? Thats dumb.
Sixth mistake: How does one get 12 aliens out of 8 people???????
Seventh mistake: One person still having an alien inside did not birth yet - so how does one get 12 aliens out of 7?
Eighth mistake: Why put more than one alien in a holding cell?
I could go on, but as you can see this movie is kind of silly. But it is fun to watch.
