Feels dull and not funny. Thor's character from the previous films got absolutely destroyed. Gorr was irrelevant and felt underdeveloped: might aswell not be a character in the movie. Nothing connects with anything and there are many things that feel either cliché or not based enough to happen.
Visual effects are okay. For the lore of MCU, it's a meh. Wouldn't watch it again, wouldn't miss it. If Thor was more Thor (like in Dark World or Infinity War), movie would be incredibly better
