I have watched and finished 2 series in the past week, one of them being a psychological thriller and the other a sci fi suspense. The former was an popular old IP from years ago I knew all the major spoilers but never actually watched it, I knew what would become of the protagonist and the final episode, I Knew of a major spoiler mid series and I knew 60% of the characters from memory, but I forgot all the details, some scenes were embossed in my mind and I remember them vividly, but watching the series now felt really amazing with every episode I felt this was the greatest thing I've ever watched, nothing robbed the enjoyment for me.
The Latter was a new series for me, I went not only without spoilers but I knew nothing of it aside from the title. it was an okay watch it managed to get me curious through and through, the ending was heart warming, I preferred the former series because regardless of spoilers it had an amazing plot and terrific storytelling.
