My most lasting impression is of this movie is Hela heaping destruction and death on all she could touch. Overall, that part was tasteless and crude.

A good story establishes premises or rules and works within them. Usually, there will be one or two new additions or changes along the way to provide a plot twist. When done well, the twist is foreshadowed. The Marvel series of which Thor is a big part has established these rules. Thor and Odin are godlike creatures, if not immortal ones. Thor's hammer is indestructible. But within a very short period at the beginning of this movie, countless of these rules were abolished or changed. Odin dies. Thor's hammer is destroyed. Hela is unstoppable even by an army of godlike Asgardians. Thor is enslaved through a device that controls him via pain. In other words, virtually everything we have come to know about Asgard and its people is rewritten. And Hela appears to have no rules governing her whatsoever in terms of what she can do.

Then to make matters worse, the rules change and the indestructible Hela becomes beatable.

The plot is weak because the movie relies heavily on fight sequences and sophomoric humor. Often times the humor interrupts the flow of the movie. Hulk is a disappointment.

As is often the case with PG-13, there is much crude innuendo.
