It depends on the show. If it's a network TV show, I'm okay with several month long breaks. If it's a streaming show, no. I watch the show when they've announced AND scheduled the final season.

Yes, I miss out on the social media chatter while airing, but there's always rewatches going on and I can start new Reddit threads like, "I'm on S2 and ..." to get some feedback.

I'm fine with the fact that it can take years to make some of this great TV, but I too don't have a memory good enough to watch in real time. On rare occasions, I will use YouTube season recaps if I caught something live, but if I know its a show that is likely to have years between seasons, I just wait usually.
