About the only thing that I didn't really like about this movie was Frigga getting fridged. I'm just... I know it was done for the intensity of Loki's emotional response, to facilitate Odin's breakdown and to showcase how hardcore Kurse was as compared to Malekith (Frigga slapping down Malekith with like no effort was one of my favourite things), I just... I'M NOT HAPPY THAT SHE'S DEAD. SHE WAS A STONE-COLD BADASS QUEEN.
Also: Odin, your douchebag is showing, big time. Stop. Okay, or not. I'm not clear on what happened to him in the end. Has Loki killed him? Did he Odinsleep again? He was showing signs of fatigue after Frigga's death, and emotional stress did play a part in him going into the Odnsleep in the first movie. Nothing like becoming a widower for emotional stress.
Also, I wonder if Loki realizes that he essentially pulled a Peter Parker? Out of spite, he told Kurse how to get out of the prison, and as a result Kurse was able to save Malekith from Frigga and kill her. If Loki knows that Frigga's death is at least partially on him... yay, yet more stress on his almost nonexistent sanity!
Loki's back and forth in this movie was wonderful, though. You just seriously never knew where to stand with him, which was just kinda perfect. I nearly died laughing at him just sitting there reading during the fighting in the prison. Then it was cheers for Thor for handcuffing him instead of giving him a weapon, then a lot of "d'aaaaaaaaawwwwwwwww" over them bickering and snarking like brothers, and then "oh, Loki, seriously?!" over him stabbing and beating up Thor, and then "YES YOU TWO ARE BEAUTIFUL" when it turned out they were working together, and then "ILLUSION ILLUSION ILLUSION... illusion...? Right? Please say illusion? WAIT ARE YOU SERIOUS NOT AN ILLUSION" when he died, and then "FCUKING KNEW IT" when he didn't, and then "dafuq is he planning?!" when it turned out Odin had been replaced by Loki at the end.
Really, seriously, my personal headcanon is that Odin is in the Odinsleep and hidden by Loki, who knows that Thanos is coming and has plots concerning that, although I also wouldn't really put it past him to have killed Odin and then proceeded with the Thanos-related plans. Loki is so Oedipal it almost hurts.
I did seriously cry when Odin was holding Frigga's corpse, though.
Also, through the Loki-haze, it's easy to forget that Darcy is the best character, even though she really, really is. "Gimmie your shoe!" Her and Ian... XDXDXDXD
AND SELVIG RUNNING NAKED AROUND STONEHENGE, WTF XDXDXDXDXD Topped only by Thor hanging Mjolnir on a coat peg for hilarity.
Jane was really, really awesome as well. She survived having the Aether in her, science'd Asgardian magitek, and then basically defeated Malekith with science and Thor's assistance. Girl is epic.
Also much approval for the long, lingering shot of Chris Hemsworth's naked chest. Very much good, yes.
I'm also, I must confess, seeing a lot of Star Wars in my MCU. I have literally no problem with this whatsoever, especially since they're using Natalie Portman much better than George Lucas did.
And that stinger... INFINITY STONES, YOU SAY?! (Does this mean Avengers 2 is going to start with half of the sentient population of the universe vanishing? Because that's kinda how Infinity Gauntlet plotlines tend to start.
