It really takes some effort to watch all three movies in a trilogy.
As well as devotion, time, money and interest! I mean, if you're not tied to the original, chances are you won't be seeing the sequel (let alone the threequel or fourthquel or fifthquel or sixthquel!)
Well ... here it is. All the nineteen trilogies that I'VE seen (as of 2020). The real question is though, have YOU seen all of them?? COVID-19 ain't vanishing any time soon, so may time be on your side .........
