This has to most underwhelming movie of Thor universe for sure. Firstly starting off the review by saying Taika Waititi why do you add so much Humor in a movie that literraly suppresses the screenplay and story, As of story nothing new typical marvel movie.
Firstly let's talk about strenght of the movie, Visually this movie is top-notch, acting department is good especially Christian Bale and Natalie reviving character of Jane foster is good and Chris was also decent, love triangle between Mjolnir, stormbreaker and Thor was hilarious, some humor and puch line were good and Bgm especially those classic folk song typicall waititi touch were good, Action scenes were average, apart from Jane last fight scene which was excellent etc
Now the weakness, First of all I was having a huge expectation from Taika waititi that he can do something out of the box, something new like we have seen from Jojo rabbit but it was complete opposite, the literal negative part was it's Humor, It was over the top I mean 75% of movie was some comedy sketchy movie with little bit fighting and romance, The silliness was so more that it becames parody of Itself!, Second dissapointing thing was Gorr the god Butcher, I mean what on earth were they thinking when they were writing about his character, first of all he was the one who kill the gods but there where was no backstory about it, Film runtime is about 2 hours and he is present in like 20 min, I mean common this was the most anticipated villain, the only seriousness in movie was during gorr scenes, Action scenes were average but it lacks the wow factor in action scenes, Rushed screenplay, the emotional angle was there but was lacking little bit of touch it was messy, they tried to create romantic angle between Thor and Jane but it was completely washed but that uneccessary comedy.
If the movie had some guts to try something out of the box had taken some risk, create less humor then it would have great potential to be best Thor movie. Don;t forget it has post credit scene
