Ok, yes, the ending was cool and unexpected, but I don't think this would work as well as the original Vader ad would've for non-geeks.
Why? I'm 99.9% sure more people have heard of Darth Vader than Thor, especially the Marvel comics version. And of those, more people are likely to know that Vader can move/affect objects by gesturing.
In this ad, you have a kid wandering around dressed up pointing an oversized toy hammer at things. And I imagine most people are just going to be going "huh? What's he trying to do?" unless they've already seen the Vader ad, in which case they'll at least have some idea of what's going on. If they haven't though, I imagine they'd be pretty lost.
