This is one of the few museums I'd actually buy a yearly membership to if I lived in the area. MoPop is set up with several smaller exhibits that act as their own standalone experiences. If you were to only visit one of these "worlds" each time you went, you could easily spend hours within each exhibit.

Each exhibit is pretty dense and filled with information so you might start out ambitious and try to read every card, but taper off towards the end. The exhibits that pertained to pop culture in the movie/tv sense were: Fantasy, Horror, and SciFi. Each one scratches the surface of what these genres look like in the media and could easily be expanded into a whole museum in itself, but the overview gives you a fun glimpse into how the genre plays into the entertainment industry through costuming, tropes, and interactive displays.

While I visited, there was a Marvel exhibit on rotation and was the most substantial exhibit there. It was an extra $8 on top of the admission ticket but worth every penny. It was a good mix of comic book history as well as pulling in the more modern showings of Marvel characters so that diverse generations could enjoy the exhibit without feeling like it skewed too one way or another.

This a museum you could easily spend all day at, but I would recommend going at off peak hours if possible so you can take your time and experience some of the more popular exhibits like the Sound Lab.

I would definitely go back on another trip to Seattle and highly recommend it to anyone else visiting the area!
