In 1977, a bunch of characters in their 20s and 30s rebel against a father figure that's turned away from a vaguely defined spirit of goodness in search of power and domination. In 2015, that same ragtag crew have been fighting the forces of evil for almost four decades but are now faced with the problem of their early 30's children flirting with the same draw of power and domination.

I had a great time watching this. And I was really pleased with the casting. Finding actors who could actually have fun with something so culturally freighted was pretty impressive.

But I'm sick of being told how important my parents' generation is.
