Well, moved overseas in 2021. Since then have gone 3 times, the lack has more to do with nothing really interesting being released.
Of those 3, Dune 2 as IMAX was one of the reasons.
Pre 2021, think 2019 was the last, as had one friend obsessed with doing movies, think averaged 3 time a year or so, had more to do with getting everyone together, eat out, etc., but this is down from like every month pre 2015.
Prices just kept going up, and the quality didn't really match, including feel like stopped being the target demographic for a lot of the movies as they became more and more cookie cutter.
