And 2001! Best Sci-fi movie ever imo.

Not bad list overall, but some weird rankings.

Anyway, Moon is no.1 for me (not that I watched everything from the list).

Agreed! I also like your top 20 list. Seems like we have similar taste in games AND movies

Yes we probably do.

Glad to see a Wong Kar-wai fan btw, those are hard to find. I adore most of his cinema, specially the prequel of 2046 "In the mood for love" wich is one of my favourite films ever.

:)

I'm glad to see a Bong Joon-ho fan, myself. In addition to Snowpiercer, have you seen The Host?

Big fan of "Memories of Murder" and I liked "Mother" a lot too.

I enjoyed "The Host", good movie, but didn't really loved it as much as "Snowpiercer" and the two I mentioned.

To be fair las time I saw it was like 7-8 years ago, so my perception today may change for good or for bad, I may have to see it again.

I think that's totally fair. The Host is good but nowhere near as good as his best.

What would your top 10 sci-fi of all time look like?

Make this three. I love Wong Kar-wai movies, but I still think most sci fi movies this century are crap.

10 - Solaris (Tarkovsky, 72)
9 - Ghost In The Shell
8 - Mad Max: Fury Road
7 - Nausicaä
6 - Star Wars Episode V
6 - Matrix  
5 - Metropolis (Fritz Lang, 27)
4 - Wall-e
3 - Alien
2 - Blade Runner
1 - 2001: Space Oddissey

Something like this, depends on the day. 

10. Snowpiercer

9. Dark City

8. Close Encounters of the Third Kind

7. Mad Max: Fury Road

6. Blade Runner (director's cut of course)

5. The Day the Earth Stood Still (1951)

4. The Empire Strikes Back

3. E.T.

2. Metropolis (1927)

1. 2001: A Space Odyssey

Five in common! Plus same #1. Not bad at all!
