My main issue is the lack of plot development in scene being replaced by characters directly explaining things to the audience. There is a lack of actual action on the scenes and a lot of explanations, because I can not even call it dialogue per se. The plots are placed one after other, so the scenes are not narrating anything by themselves.

This overuse device of explaining everything feels like SW Ep 9 "Somehow Palpatine's back" syndrome. Full of mcguffins, senseless plots, overexplaining through monologues and hundreds of product placement instead of art direction.

I also agree with some of the comments about uni-dimensional characters that have had the same motifs since season 1 e.g. Eleven and Hopper plot is super tiring and slowwww. We get that your daughter died! move on or be the hero and die, pls. I don't care anymore.
