I do this for a few things, movies in particular. For me most recently, I'm planning on watching Bo Burnham's Inside this weekend, for the first time since I watched it shortly post-release. I wasn't really intending to wait *checks watch* nearly 3 years on that one, but I definitely felt it needed some space before a rewatch.
Anyone else treat certain pieces of media similarly?
For me it's books. I try not to read The Discworld series too often. Same thing with a few of my favourite books: Jane Eyre, Ivanhoe, Villette, etc. I also try to ensure a long enough gap (few years) between each read so that details of the books become a bit hazy in my mind and I can enjoy my read almost like the first time.
