In completely random order:
1. The Scent of a Woman - My God, I watched Scarface, The Godfather, Heat and all other Al Pacino classics, but I still think, this is his best performance ever. Amazing and funny movie.
2. Inception - Nolan's either best or 2nd best movie ever. The other would be...
3. Memento - I watched it 6 times, each time getting a different take on the plot.
4. Groundhog Day - Bill Murray at his finest. Really damn funny as well.
5. Equilibrium - This movie gets a lot of hate, but I personally found it really, really good. Also, Christian Bale murdering tons of dudes. Speaking of Christian Bale murdering dudes...
6. American Psycho - Another, great performance by Bale.
7. Reservoir Dogs - Best film by Tarantino, hands down. Almost no action, but DAMN, those dialogs are made of gold.
8. Snatch - Amazingly funny + great performances by Jason Statham and Brad Pitt.
9. Monthy Python and The Holy Grail - All of the MP's awesomeness packed in one movie.
10. 300 - What? Despite cheesy dialogs, it's still an amazing action film. Also, it became a favorite among me and my friends after we played a drinking game - one shot after every 'Sparta' or 'Spartans' (2, one after another during 'THIS IS SPARTA!' scene) spoken in the movie. That meant about 10 shots in 20 minutes. After half an hour, there was no sober people remaining.
