Horror - Dawn of the Dead 78 version, also one of my overall favorites.
SciFi - I guess Star Wars 4,5,6,7 and Rogue Squadron. Also Family Guy Star Wars.
Fantasy - LOTR and Hobbit movies. Also
Western - Unforgivin
Action - The Raid
Comedy - So many. One Flew Over the Cuckoos Nest. (Comedy/drama)
Goodfellas for me has to be top.
Closely followed by Usual Suspects (possibly the only film I’ve never seen the end twist coming).
Then for an obscure one:
Dogma
As a series:
Alien or Lethal Weapon depending on my mood
In hindsight, yes they were! BUT, had they stayed true to the original concept & landed the Predators on the Alien’s planet to hunt them - how much better would that have been?
The Predators is not very scary, beside from a fish face that they most of the time masks up. On the other side Aliens is very scary, and only became more like the true nightmare after I played the game Alien: Isolation…
Eika showed me a great movie called “Sunshine” the other day. The story was haunting, and the cinematography was beautiful. Plus, it starred Cillian Murphy… enough said.
