Crikey, there are so many... all the way up from the original 12 Angry men to Jean de Florette, via GlenGarry GlenRoss and Raiders of the Lost Ark all the way to Apocalypse Now Redux and the extended version of Aliens.
Aliens, Terminator 2, and the Abyss must all be enjoyed in the extended/directors cut editions.
Hard question.. but a decent (not the best) movie to watch would be ready player one or interstellar
I'm not sure.Interstellar is an odd one isn't it. It really does seem to equally split people into the either like it or hate it camps.
