Battlestar Galactica Exhibition at the EMP Museum in Seattle.
The exhibition itself was pretty small and didn’t really offer much to die-hard fans, other than a great feeling of nostalgia and an urge to re-watch the entire series again. But it made someone, who’d never ever seen an episode, want to start watching the series. So I think it wins on that front.
The Avatar exhibition was much more extensive in terms of design and production materials on display, but I haven’t seen the movie and I don’t really care to.
The Sound Lab they have going is pretty awesome. Wanted to play around on the keyboards but my broken wrist cock-blocked me.
