I finally saw it on Disney+ and I didn't love it. It was okay. I thought that the setup was good. Gorr's backstory, the updates on Jane, the reintroduction of New Asgard, and the battle with the Guardians. But then things kind of fall apart, almost like they ran out of budget. It goes from a big colorful battle at the start to a boat in space, one room at Omnipotent City that is basically just filler, a black and white shadow planet, and some dark cave thingy with some mediocre action that we've seen in every Thor movie to that point. Compare that to how epic the fights were in Ragnarok and it is a clear downgrade.
There also a big issue in that we just saw this movie done a lot better earlier this year in Multiverse of Madness. The characters arcs for both the hero and the villain are very similar as is the overall structure of the films. Except MoM did it far better. For example, midway through the films the hero gets captured and has to face the ruling elite of the world they are in. In MoM, Strange learns how easily he can fall to temptation and the destruction it could cause, something that is build upon later when he meets the Evil Strange, and it leads to a great scene of Wanda assaulting the place like something out of a horror movie. In L&T, they get a lightning bolt. That doesn't even factor into the story. Throughout the movie, I just always had the feeling that I had just seen this done better.
So we get a movie carried by the performances and the humor, and that does work. But there is not much substance underneath that. Like I said, it is okay. I can watch it as a popcorn flick and have an entertaining enough couple of hours. It is TDW with a better villain, basically. 6/10
