I don't get the great reviews

Rating: 5/10 (10 July 2018)

Perhaps fans of the comic book found something in this, but ... I just don't get it.
You'd think the premise of this film--Ranarok, the destruction of Aasgard--would be front and center in this film. Instead, that's more like a side plot. Most of the film takes place on this absurd trash planet ruled over by Jeff Goldblum.
Along the way, we see the death of Odin, the introduction of Hela (who should have been a fantastic villain) and the deaths of the warriors 3 (though they get about 5 seconds of screen time before their quick demise).
So basically, Thor and Loki get stranded on Jeff Goldblum's planet during a brief fight with Hela. This, after Hela easily destroy's Thor's hammer. Thor is then captured and forced to fight as a gladiator ... against the Hulk, who just so happens to be on this planet after the events of Age of Ultron (something something wormhole on earth that didn't drag anyone else in something something plot needs to tie in other Avengers for Infinity War). Oh and somehow the Hulk has been the Hulk for 2 years ...
Thor finds out his enslaver is a Valkyrie and he must convince her to help him save Aasgard while also navigating Loki's usual machinations.
Anyway, during all this Aasgard is suffering under Hela, who has slaughtered the army, raised an undead army of her own, freed her giant wolf, and is "getting more powerful" with each passing day. Meanwhile Heimdall has been helping Aasgardians escape.
Therein lies the problem. This was two movies crammed into one and we could have done without the silliness that was Jeff Goldblum's planet. Hela was completely underused. We're told how powerful she is going to become, but we see her easily defeat Thor and Loki in her first few minutes, then she easily annihilates all the soldiers and establishes herself as ruler. It would have been cool to see her powers grow, to actually see her become this formidable foe for Thor.
Speaking of Thor, he loses his hammer ... and his hair, then with a fight against Hela later, he loses an eye. Oh and he becomes the true god of Thunder (and lightning), which is supposed to be cool, but it doesn't do much in his fight against Hela.
The other problem is how much comedy is injected into this film. For instance, when the Warriors 3 are killed, Karl Urban's character sees this and says "I'm just a janitor." Ill-timed comedy completely minimizes the death of these friends of Thor (nevermind they are never mentioned again).
Then, when Aasgard is destroyed, there's some comedic lines ... it should have been a somber moment--seeing the destuction of Aasgard (yeah yeah, I know, Aasgard is a people not a place).
I don't know, this film really missed the mark for me.
