These were the DUMBEST aliens...
...if they never ever thought about alien bacteria killing them when they invaded another world!
I mean, couldn't they have realised the possibility? Or sent scouts or probes ahead of them to find out more?
It just seems dumb to me to launch an all-out invasion of an alien world without first knowing potential problems like that.
If the story is following HG Wells to the letter, fine, then it is faithful, but I would've thought even HE would know such things! Heck, even the Tom Cruise movie followed the exact same pattern!
Dumb Martians!
The only smart aliens I've seen invading Earth in movies are the ones in Independence Day, and even though the premise is similar (advanced technology but frail bodies) these ID4 aliens didn't succumb to bacteria. Smart move on the part of that movie, that's for sure.
