What a letdown

Rating: 1/10 (3 April 2018)

For some reason I thought this was going to be an intelligent cool sci fi adventure. Boy was I wrong.
This is one of the stupidest movies I've ever seen. And it runs at such a snail's pace you may start to doze off in the theater.
Several people have listed all the scientific and logical inaccuracies, so I won't bother since they are numerous.
Just a few nits...Why did it take 500 rounds of ammo to kill a gator. And what's the deal with that giant rat with no skin on it's face? And then that alien robot at the end. And how about the plants that grew in human forms? How ridiculous is that? The reason was given as the radio waves reflecting or something equally silly. We never find out what it is exactly and it self destructs for no reason.
Sorry, but this was too stupid to give any higher rating than I did. It deserves a zero rating for wasting our time and lowering our IQ.
I knew it was silly from the first dialog in the classroom where she states that some lone cell roamed the universe for billions of years looking for a home. Or some such nonsense. Are students really taught this in science classes today or is this Hollywood's belief system?
The movie is geared for the uninformed and those who were never taught any real science.
They throw out scientific terms to explain unreal phenomenon, but it's all gobble de gook.
I'm sure many will love it, but to those who know real science it will look like a really bad cartoon.
