That doesn't change how you have to seriously suspend your disbelief to go for it.
It's an alien invasion movie with Tom Cruise. That comes with the territory. Be happy he didn't fight the aliens as the last samurai - remember they took some tripods down on Osaka.

"Eradicating bacteria" doesn't make sense. Bacteria is an important part of life.
Harmful ones. And yes it makes sense, or at least it did made more sense on the original book.
Since they planet became barren, the Martians probably had to live an underground life on artificial sealed environments. After a long time, they probably just got rid of all malign bacteria, virus and such. It time enough passes, they might even forget the concept. They had to invade Earth because they were in desperate need for natural resources, what means they had to consume them. And because mankind's technology was getting advanced too fast, they’d be somewhat unprepared. On the movie, this angle is lost and it makes less sense.

If they did somehow evolve beyond it, then they'd have to so seriously evolve that no bacteria affected them, including Earth's. It's really weird that they were observing us for millions of years and didn't understand the concept.
As the movie states, we were the bacteria for the aliens. So the aliens wouldn't mind about the bacteria of the bacteria. If the most powerful forces on Earth couldn't harm them, they shouldn't worry about anything else.

It's really weird that they were interstellar conquerers and didn't see bacteria on other planets.
We really don't know if they invade or even visit other planets. It’s also too much to assume that bacteria would be the same all around the universe.

It's really weird that their ships weren't air tight (chemical/biological and other weapons would've worked on them then), and it's really weird that they had no other resources: all their forces were simultaneously subdued.
It doesn't matter if the ships were air tight, because they came to earth with no resoruces but themselves, and the ships were already here. They had to use Earth's supplies to live, and that's where they lost. They didn't had other resources either because they couldn't or because they thought they didn't had to. Arrogance, again.
But that’s not all. Energy shields are not the most scientific of things, there’s no such thing even in theory, I think. Tripods are not the best way to produce walking vehicles. What’s the point of preparing to destroy mankind when there was no mankind to be destroyed? And what’s the point of the blood-plant thing? A lot of things on the movie don’t make much sense.
