Phase 2 After credit scenes
IM3: talking to Banner. Awesome! It made the narrative in the film make a lot more sense
Thor 2: Mid credit, okay. After credit, also okay. Not terrible though. Liked the GotG tease.
Cap 2: Mid Credit: WS, good! After credit, teasing AoU, also good.
GotG: Dancing Groot, okay. Howard the Duck, okay
So, Phase 2 has provided one really great after credit scene and the rest have been average to good. I personally don't hate any of them, but the average ones don't really stand out either.
