It still is for network tv shows, that still adhere to the 20+/- episode a season format, especially those with higher production costs due to bigger sets and special effects.
With smaller, 8-13 episode streaming shows the budget remains the same or is even bigger so they are able to afford movie level sets, costumes and special effects and it shows. I thought about that in one season 2 Mandalorian episode where the visuals were just spectacular and could have easily be in a big movie theater.
It seems Disney is going all in with their slate of Marvel shows next year and i am seriously considering renewing my subscription (just Mandalorian and a ton of MCU movies and Disney Animation, which i've seen hundreds of times, was not enough to justify the costs).
The trailer looked gread but i kind of missed Falcon handling the shield as we have seen in a teaser, i guess the producers didn't want to spoil too much as these shows are now truly linked to the MCU as opposed to Agents of Shield that only had a connection in its first season and was ignored completely by the movies. It seems Disney is planning to run a more cohesive package now and i'm curious if and how this will affect the movies when people are not watching the Disney+ shows.
Not likely - at the end of Captain America: Winter Soldier we see his character being arrested by the FBI, so its safe to assume he was exposed as Hydra.
