Vantaggi
Frankly the main, and only reason, to work there is to work with the amazing IP. Really fantastic and deep pool of fiction. Also, since Marvel is on top, everyone wants to work with you and wants to PAY you to do this. Really like being in the catbird seat.
Svantaggi
I worked there three years and was essentially fired/laid off due to a NY HQ EVP (political play). All power in this company resides in NY and there is a small group of Executives there that control the show...even with TV and Film. These Executives are not your friends and have no interest in your growth or happiness. You will be viewed as a 'means to an end'. I've seen quality and loyal (5-10 yrs for service) fired because of the NY cabal - not agreeing with their dictates. Oh, and don't expect any of those Disney perks at Marvel. Marvel is a notoriously cheap and frugal (even with their billions in profits) company. Again with the NY management team's perview...you should be happy you have a job.
