I like the fact that they got Lou Ferrigno to voice the Hulk again (like he did in the '08 film). That amuses me for some reason

A little surprising to see such a spectacular Bechdel Test failure from a writer/director so notable for his awesome lady characters.

I read that almost as Odin taunting Thor or at trying to get him motivated. Because he's basically saying you are no longer worthy to be Thor. Anyone else wanna give it a shot? And yes, it is just a spell to make sure Thor can't pick it up and regain his powers until he's worthy.

It's basically a combination of Hercules and Arthurian legend. The gods remove his godhood and turn him into a man, and he needs to prove that he can be a true hero before he can lift the sword from the stone and become a god again.

I'm also not a fan of the whole you just have to be really strong to pick up Mjolnir thing. It kinda undermines that whole otherworldly powers thing that asgard has going on. I've always seen it as Thor having some sort of deep seated almost magical connection to Mjolnir, which is why he can call it to him at will, and it can make him fly etc etc.

It's worth bearing in mind that Mjolnir is merely Thor's weapon of choice, it may have powers (principally over weather and lightning, and allow him to 'fly') but it's neither the source of his powers nor his only power (as evidenced in Avengers when he's fighting without it). It's easy to confuse what happened with the hammer in the Thor film, which was a specific test of his character, with Thor generally.

There have been other wielders of the hammer throughout the comic run, and some have been able to use Mjolnir's powers, but none to my knowledge have stripped Thor of his own natural ones. (In fact, there's a long run where Thor fails to prove himself worthy and ends up killing most of the Marvel heroes without it anyway.)
