You completely misinterpreted those. I'm not saying make both films the same. The first film would deal with Thanos and other villains collecting the Infinity Stones and practically kicking everyone's ass. The Avengers are in the movie, obviously, but wouldn't be around as much as you normally see them. Thanos should have a TON of screen time in this movie.
Everyone *****es and moans about Marvel not getting their villains right. Well here's their chance. This first film should show more Thanos and less Avengers, while the 2nd film should be more Avengers, less Thanos. If they treat him like they have nearly every other villain in the MCU, then what's been the point of building him up?
The end of the first film is not gonna end with lollipops and rainbows. So I'm expecting to see more of the villain than I am of all the heroes. I also expect the ending of the first film will be Thanos with all the Infinity Stones. Almost reminds me of Voldemort retrieving the Elder Wand at the end of Harry Potter ATDH P1
