Pros
Lucasfilm, under George, was a wonderful company full of innovative minds who all collaborated together to put out the best products. The company culture was familial with everyone working towards the same goals. Campus was beautiful, food was awesome and work/life balance was one to covet.
Cons
There wasn't a lot of opportunity for upward movement because no people rarely left. This speaks to the company culture in a positive way as most remained with the company carrying the title of "Lucas Lifers" but that also meant one could stay in the same position for years and years. Also the company was notorious for paying below market. It was simply a known fact that everyone lived with because they loved working there but in today's Bay Area market, it could make life quite hard.
