It feels like the show still isn't overly special for me, visually it's amazing but it feels like it's being more generic than it should with "evil russians!!!!" as generic mysterious antagonists and other bits. The show was at it's best really when it didn't try to cram in lots of sci fi horror but was more so about a mystery in a small town, it also reveals a lot more than it should to the viewer which takes away a lot from the mystery.
Also is it me or did the writers lobotomize Hopper, he's been shown in the last two seasons as being almost a completely different person now they turned him into a fat old dad when before he was probably my favorite character. They also spent like two seasons trying to find Will and now everyone just disses him lol
