Haven't seen the Disney version yet. I did see about half of the SciFi version, and it was pretty awful. The alien makeup was literally falling off an actor's face in some shots.
They also managed to make the most iconic movie location of all time look drab and uninteresting.
It's sad some people have no idea how many stories and films have taken their inspiration from Edgar Rice Burroughs' source material. Disney is probably in shock over getting edged out at the box office by yet another Dr. Seuss movie, and yet another joke fest based on an old tv show.
Meanwhile, that teeny bopper Running Man clone I never even heard of prior to a couple weeks ago, is probably going to gross even more obscene amounts of money than all of them. ;)
