Love the LOTR movies, but as seems to be the norm, can take or leave the Hobbit films. Re-watched Indiana Jones with my eldest recently, as well as Star Wars (all of them including Solo and Rogue One), he wants to do the Mission Impossible films next.
I re-watch series more often than films though, Every few years I do a Lost re-watch, even though I know it'll end up pissing me off, I'm overdue another go round tbh.
Also re-watch Stranger Things from start to finish each time just before the new season comes out.
Other series I've re-watched more than once include all 9 seasons of 24, 5 seasons of Quantum Leap (Original Series), Reacher Season 1, Supernatural season 1-15, Breaking Bad and Better Call Saul, Dexter 1-8 and Prison Break.
There's not really been an epic season that's captured the Lost/GoT (which I've only ever watched once) hype whereby there's loads of theories flying about for a while now (except maybe Stranger Things. TV seems to have gone backwards as a medium recently.
