I was thinking today, what to watch? And I remembered that season 4 came out of stranger things and I just kept procrastinating to watch it. When I thought about it, I remember season 1 really well the upside down, her powers the kids etc..., but 2 and 3, I don't really remember what happened. Something with a shopping mall , an underground lab? And giant monsters. I don't remember the character evaluations who did what, why, when. And I just thought, I can't be bothered to watch it all again. But if I start 4 and I don't get it, I won't enjoy it maybe as much as I could have. I hope season 4 won't be that forgetful.
