In that case, here's what I'd say: Tarkovsky, the director, is considered one of the greatest ever. He's not just some random Russian director, or some random 70s director. And he only made seven movies. Based on those facts alone, I would think it'd be worth seeing at least one or two of the seven. If you're into sf your best bets are Solaris or Stalker. Personally I prefer Stalker, but Solaris is also great. There's plenty more that could be said about Tarkovsky, Solaris, Stalker, or his other films, but for me at least those facts alone would be enough to take a look.
