Which is kinda funny considering he was anything but menacing in the original comics.
Sure, he was deadly. But in terms of personally he came of more like a man child, unable to take a hint that Death wasn't interested in him. No matter how powerful he became.
Yeah I'm gonna go ahead and disagree with this. Thanos was most certainly menacing in the comics given the absolutely insane shit he did to the heroes, and the reasons for which he did those things. He could literally murder any one of our favorite heroes in fucked up ways at any time, and often did for the most ridiculous reason.
The fact that he was a man child is exactly WHY he was menacing. The petty and vindictive way he would execute his enemies and the means he would use to do so were horrific. His motivations are base but understandable, and ultimately make sense because in the end all he is, is a pathetic man desperate to gain the attentions of a woman who seemed completely uninterested. I mean he literally MADE himself a girlfriend in a pathetic attempt to make Death jealous.
Thanos in the films is absolutely retarded. His plans are fucking moronic, why even use Loki as a proxy in the first film when he and his minions could literally body the universe on their own? His ultimate plan is so fucking stupid a grade schooler could figure out why it wouldn't work and is ultimately pointless.
The universe has finite resources so I'm going to wipe out half the life in the universe, never mind that people would just repopulate and create the problem all over again in a few decades, and the resources they have already depleted are still gone. I have the most powerful weapon in the universe that can literally alter reality, I could make infinite renewable resources, construct new worlds and laws of nature, but I'm going to deal with the problem in the most moronic and surface level way possible.
He doesn't even execute his enemies when he has the chance. He literally destroys the Guardians of the Galaxy and then undoes it when he leaves. Why? Who fucking knows. He has no menace, he doesn't even kill his fucking enemies when theyre not faceless npc characters. The cruelty and insanity of the original is gone, in favor of this banal sense of altruism colored by murder.
The film tries to humanize him in the most idiotic ways too, as if he isn't a monster who sacrificed his "daughter" in the pursuit of an inherently moronic crusade that will achieve nothing in the greater scheme of things. As if he's doing this shit for good reasons.
Movie Thanos is the equivalent of your average teenage twitter poster posting about climate change and how we need to eat bugs and live in pods to survive.
