I do lots of rewatching. I'm currently going through my Blu-ray collection re-visiting titles I haven't seen since 2010/2011 (thank god for the "sort by recently watched" option at blu-ray.com).
Besides that I have my usual suspects I spin once a year. Jaws and Poltergeist are my summer movie season openers (though I already watched Poltergeist in April). Other once-a-year movies are Sole Survivor, Valley Girl, Sixteen Candles and/or The Breakfast Club, Prophecy, Terror at Tenkiller and/or The Last Slumber Party, Let's Scare Jessica to Death (in October) and more.
