I thought it was great fun. It's the characters of this show that keep me coming back. One more season, correct? Time travel. Maybe agent Carter? There's a loose end to tie up from here series (at least I don't know anywhere is was tied up.)
Did they stop trying to tie into the movies after season 3 and Civil War? I can't think of any later references. It looks like season three is also when they started writing their own secret history of Hydra, and creating their own universe.
They had a very, very vague reference to "something happening in New York" in one of the last episodes of S5 that was a reference to Infinity War, but beyond that, nope. It's gone over the horizon, likely not to return. A shame, because it's AoS that actually made the MCU a place I was emotionally invested in.
