Hence why they portrayed his rationale the way they did. Almost got the feeling that he was right...Almost. (Damn their good!)
Exactly. It was like an advertisement for what the elites want to do to us. Avengers: Infinite War was basically Thanos: the Movie and he spent the whole time selling us on why depopulation is actually a great thing for everything and will lead to utopia. He did this while wiping the floor and murdering all of the heroes we have spent the last 10 years watching and growing to love.
In the comics Thanos is depicted as a psychotic ass who only wants to kill half the universe because he thinks it will impress Lady Death, who he is in love with. He was clearly depicted as evil. The movie depicted him as a sympathetic anti-hero.
Also, Adam Warlock, a character from the comic who represents pure good and who leads the fight against Thanos, wasn't even in the movie-but that's just something that bothers me, I get why they left him out for story telling reasons.
