Sometimes you just crave a comfort watch. Multiplicity is a thoroughly enjoyable ride that I've enjoyed on multiple rewatches since the "record your favorite movies off TV onto a VHS" days.
Sure, the premise is absurd, but the execution is fun, delightful, silly, amusing, and sweet in ways that simply jive with my taste and consistently keeps a smile on my face. I also love the underrated versatility Michael Keaton displays in his portrayal of the protagonist as well as the three clones who all have their own distinct personalities.
It may not be The Best™️ but it firmly being on my personal 1️⃣ top 20 "most-rewatched movies" (irl, not LB) and my 2️⃣ top 20 "most-quotable movies that I still frequently quote in my daily life" list makes it a winner in my book. So, yeah...I love this movie.
