Thor: Ragnarok was a huge success for Marvel Studios, due in part to Taika Waititi's comedic chops, so why didn't Love & Thunder work in the same way?
Tried to do too much and out do Ragnarak was the issue in my opinion.
I really disliked all the dialogue with the weapons as they have thoughts & feelings.
This Thor was certainly the worse of all the Thor movies.
You see alot of comedy sequels that were never as good as the original. If you go back and watch them you'll notice most generally the sequel has more jokes/comedy in it. So movie gets overly saturated by it. Also the fact they force the comedy scenes more to 1 up the previous film. Add those together and its too much.
