Nice teaser, didn't show too much. Hella interesting to see her family outside the Avengers. The action looks good too, only thing I'm not a fan of is Taskmaster. We've gotten some bleh looking comic villains who look great in the MCU, did not have to make him look a lil worse.
People complaining about CGI not being amazing on a teaser trailer when it's still 6 months to movie release?
This is pretty standard for teaser trailers.
