Nope. I'm right there with you. What puzzles me is that this is yet another mediocre film celebrated as being among the genre's best. It pains me to say it, but Ethan Hawke was right, especially after this season of superhero flicks.
Anyway, one of my main issues with the film is that it lacks the personality, charm, and wit that the rest of Marvel's catalogue has been rife with thus far. This isn't the first film in the MCU to have a fairly generic plot, but it is the first to feature such flaccid characters, dialogue, and interactions. This is the area where I've been forgiving of these films in the past, as they never failed to deliver on the character front, but with this film, I can honestly say that the only two characters I gave a damn about were Loki and, surprisingly enough, Frigga. Rene Russo did an excellent job considering her small amount of screen time(I'd say the same for her in Thor, btw, her role just wasn't quite as pivotal in that film).
Also, with regard to the characters, many of the relationships from the first film were either butchered or tossed aside. Selvig's paternal relationship with Jane was dissolved completely, while Thor and Jane's romance felt very matter-of-fact and obligatory, completely lacking the charm and chemistry that was previously there. Oddly enough, Darcy and her buffoon of an intern somehow managed to fill that particular void, having more charm, wit, and tension than that of the two leads, but therein lies the problem - I'm not interested in seeing a Darcy romance, so it didn't resonate with me at all. The Thor/Loki subplot was exceptional, but every other relationship, Thor/Odin, Thor/Warriors Three, was glossed over in this film; it was about as soulless as it could get.
I also didn't like how trivial the important events of the film seemed. The 9 realms are at war, the universe is on the brink of extinction, and it was all very ho-hum with the way it was presented. The former itself could have made for a very compelling film in its own right, but again, the entire affair was swept under the rug as if it were just another walk in the park for Thor & his amazing friends. I attribute this directly to the lack of build up and tension, which falls squarely on the shoulders of Taylor. Everything was thrown right in front of the audience without the proper build up; from the Aether possessing Jane(a weak pretext for their reunion and getting her to Asgard), to Malekith's awakening(straight outta nowheresville), the invasion of Asgard, and that sad excuse of a plan by Thor and Loki. That was the epitome of awful writing - let's march right up to the villain's doorstep and hand him the MacGuffin he's been searching for all along. Not to mention the fact that Malekith was keen enough to sniff out the Aether to the point where he knew that it had possessed Jane and tracked it to Frigga's chambers...so after he's deceived he leaves to search for it...where exactly? They shouldn't have written themselves into such a corner in the first place, but I point to this as it simply highlights the pinheaded writing of the plot as a whole. Malekith, for all his huffing and puffing, was about as insignificant as a headlining villain could get. Talk about criminally underutilized, his look and demeanor was excellent, it would have been nice if the audience was given a reason to care about him in the first place. I'd compare him to Vanko, in that the character was well acted, menacing, and intriguing enough at first, but simply wasn't given much as the film went on.
It wasn't all bad, as I said before I enjoyed the interactions that Loki and Thor had, as well as Frigga's contribution. The climax was well done, and the way they disposed of Malekith was pretty clever if nothing else. For as lukewarm as the plot was, Loki's deception is potentially earth-shattering, depending upon how Feige & Co. decide to move forward with it. I do, however, think that it revealed a bit of a plot hole, in that Loki couldn't have known that Thor was going to save the universe, effectively securing his little coup d'etat(especially after that fiasco on Svartalfheim). The whole universe being destroyed thing would have really spoiled his day in the sun after all, and about the only way I think this could be explained away is if this entire little adventure was an elaborate illusion by Loki(awful idea). That wouldn't exactly justify the existence of the Aether, but enough on that.
In spite of my criticisms, I don't think it was a bad film, just a very average one. The humor was well done, the action well shot and choreographed, and the rest of it was entertaining enough to sit through...it was just all kinda ho-hum. Not exemplary by any means, unless of course the example to be illustrated is mediocrity on an inflated budget.
