personally, Ragnarok had no serious moments that actually added any stakes. Infinity War may have elevated what Ragnarok was trying to do, but the battle on Asgard literally made the whole thing comedic relief.
As someone who also saw this at the premiere, I thought this movie quite frankly, sucked. I'm not a fan of Waititi as it stands but this was just trying too hard. Like Ragnarok, no stakes with a very thin plot where its one emotional payoff is also alas, redundant in the grand scheme of things. Really wish Thor got the proper standard of being the mightiest Avenger that he deserves.
