I'm just not sold on the Thanos design changes. The lack of helmet, the wife beater and the thinning out all feel like downgrades. This should be one of the great villains in cinema history - some who should stand aside Vader, Voldemort and Sauron. But this design looks forgettable. Maybe he'll work on screen, but I'm also dubious about casting John Brolin. Thanos should be kind of crazy, angry at times and gleeful at times. Unhinged. A bit like a purple Ramsey Bolton. Josh Brolin just dies headmaster angry and he's brilliant at that but it makes Thanos a bit one more.
Nic Cage would have been an amazing Thanos.
