I remember getting my Dad to take me to see this in the cinema. It must have been a re-release just after Star Wars. Now, I didn’t get to see SW at the cinema, and this was space so - I thought it’d be the same. It was not. 8(? maybe 10-11?) year old me was not ready for 2001. I found it dull, and my Dad never took me to the cinema again.
Of course, I’ve seen it since and it’s a masterpiece but… sad memories.
