Pros
Great people, some fun projects to work on (comics, movies, cartoons, etc.). Casual dress code. You get to go to movie screenings, conventions, get discounts on toys/swag. The brand recognition and positive associations with it are pretty great. People love the characters.
Cons
Shockingly stingy. No real career track, advancement/development programs. Easy to get stuck in a rut. The company does not care about investing in its people and their morale. We would get yelled at by the CEO for using too much paper when printing things out and had to recycle office supplies like file folders instead of getting new ones. The company Christmas party was moved from an outside venue to a buffet in the conference room. They used to sell merch internally cheaply (you could get a t-shirt for $1), and then they started jacking up prices a ton (t-shirts for $15+). For a company this successful, there was no reason to be so cheap.
