I watched it again last night. I still like it and suspect it will be a staple of July Fourth TV for a longtime to come. But why on earth haven’t they made a sequel yet? Please spare me the quasi-rational response that they can’t have a sequel because the aliens were defeated. One could certainly imagine a sequal begining with millions of aliens spilling out of the crashed alien ships in order to fight a pitched ground war. Plus, there’s always the issue of reinforcements. If Spock can be brought back to life, Hollywood can churn out a few bazillion more aliens. Indeed, speaking of returning aliens, believability never got in the way of Aliens, Aliens III and Aliens IV (they should have stopped with Aliens, of course). And ID made a lot of money. So what’s the problem? Surely it’s not the high-standards of the cast?
