Pros
Really smart people doing really interesting things with real time rendering, pre- and post-viz and virtual production. A good chance you'll be working on big name properties (Marvel, Star Wars, etc). Willing to work remote for those jobs that do not require being physically on set.
Kontras
Awful time off policies. Contractors get almost none. Even staff only get 6 days vacation. Also a MANDATORY, UNPAID two week furlough between xmas and new year. If you want a paycheck during that time, you have to use vacation (and NOT sick time). Regardless of your employment status (staff, contract, etc) you will be laid off the MOMENT work dries up. They might ask you back in 4 weeks, but they have no problem booting you to save on the benefits costs. Do not count on their generosity.
