I never said any of that. I dont think anything should be overlooked, but not every scene is there to be mined for emotional and dramatic importance either. Some scenes have very simple purposes, and do not require as much from the performers.
If a scene is being acted at all, then it should be acted well. Not acted
more, acted
well. In my view, Momoa's acting in that scene - and in pretty much every non-action scene he was in - was poor not because he didn't act
more, but because he didn't act
well. I don't think I can put it any more simply than that. I don't drop my standards for any scenes when I watch a movie, and with this movie in particular, I never needed to, because every main actor aside from Momoa gave a great performance in every scene. Even when it wasn't an especially dramatic scene. Even when they were delivering exposition.
Your characterization of Momoa as "half-hearted" is not something you could ever substantiate so you may want to drop it. You don't get offers for work like he gets if you are dogging it.
Nothing about calling Momoa's performance half-hearted suggests that he himself is overall a lazy or apathetic person, but nevertheless, Momoa's usual line delivery is by its very nature low-effort, because his laid-back, easygoing persona is part of his charm. I don't think it's good acting, but it's clearly popular, and that's why he's had the success he's had.
Also, if you think characters having varying emotional depth is handwaving then you may want to go back and have a look at fictional characters again because it's just a fact.
Of course, but in this case, it's just coming up as an after-the-fact rationalization of a poor performance. If Duncan in particular is meant to be emotionally shallow, the logical question to ask is
why, and an answer of "because otherwise it means Momoa would have given a bad performance" isn't good enough. Characteristics are there to serve the story, and they can and should be excised if they aren't doing that. So why does Duncan smirk his way through his report with the same energy he'd give off if he were asking his buddies to meet him at the local bar for drinks? Is it for comedic effect? No. Duncan clearly isn't taking anything that happened to him seriously, but there's nothing about his report that's particularly ha-ha
funny. Is it meant to provide a contrast with the more serious characters he's making his report to? No. Those characters don't really respond or show any particular reaction to Duncan's demeanor. Is it meant to provide a contrast with Stilgar's subsequent appearance? Also no. Stilgar does clash with the other characters, but it doesn't really have anything to do with how Duncan presented his report. In short, I don't believe that Duncan is simply meant to be emotionally shallow, and I certainly don't believe that he was ever intended to be the dudebro Momoa portrayed him as until Momoa ended up in the role. The end result is that we have a bad actor giving a bad performance in a room surrounded by great actors giving great performances.
Welp, I have absolutely no desire to ever read your opinions on fantasy if that's how you feel about Conan.
And it definitely makes sense why you dislike Jason Momoa.
Oh, come on, can you honestly say I'm wrong? There are some stories in which Conan is an absolute cock.
"The God in the Bowl," for instance. Conan maims multiple innocent guardsmen in that one. You know that's just not cool. And I haven't even seen the Conan movie with Momoa in it. Maybe I should watch it and report back.
