I don't really get the big deal either way
Do you not enjoy the show? Or does your enjoyment rest on whether or not the movies mention it?
Show bends over backwards to flow with the movies
(think about how awful Season 1 was before the Winter Soldier twist, which they even used as an excuse)
Now with all this Inhumans stuff they have they could literally go crazy with it but nope Inhumans aren't going all out in the movies so they wont allow it.
Coulson could destroy every single Hydra base, weapon, soldier, etc but if movies need another branch they have it.
World wide threats but you can't call your buddy Tony or the shield agent Captain America(understandable but valid complaint with SHIELD/Coulson involved).
Can't even show the 2 top SHIELD characters thanks to the movies.
Netflix shows and Carter don't have this problem because
1. Its based on freaking SHIELD.
2. Coulson is friends with the Avengers(who themselves were a creation of SHIELD).
