I really liked how they built up Thanos. It worked and worked well. You understood his stance, but he was still wrong. He was absolutely the star of the film.
ehhh...
Don't get me wrong, I liked Thanos as the villian... but his motivation is so flimsy to me.
Finite resources in the universe. Sure, with you so far.
Life cannot continue to expand uncontrolled and be substained on the finite resources. Okay, I'll accept this premise.
Thanos plans to gather a source of limitless control over all time, space, reality, etc. Makes sense.
Thanos then plans to kill half of all life... instead of using this reality warping device to, I dunno, create more resources?
Like, dude, you killed your daughter and it made you all weepy eyed. Bring her back and alter reality so that life doesn't even need food to survive. Look, I just cut down on the resources needed.
Also, I'm gonna need some more background on this "extinguish half of all life" thing. Did he just kill half of the plants and animals as well? Half of all bacteria and microbes? Seems like that would dig into the finite resouces pretty bad.
Oh, and that helicopter (Thanoscopter?) crashing at the end... that probably killed some people. Are they counted in the half that died? Stan Lee has a bus full of kids going down the bridge when he disappears, causing the buss to veer off the side od the bridge and the 50 kids onboard to drown (sorry Spider-Buddy). Do they count towards the half? Ohhhhh.... a pregnant woman turns to ash... the fetus? Is it a person? Does it count? Might have just solved the abortion debate here.
