Ordered pizza... what movie should I watch?
What genres are you into? :D
If you want oldie but goodie comedy, I recommend The Blues Brothers. Gross Point Blanke is also delightful and amusing.
If you like good old fashioned gore fun, I suggest the first Alien movie. And the second. Skip the third. Watch the fourth. Mhmm!
If you like anime, RWBY of course! Eden of the East is also quite lovely, Samurai Champloo gives me the giggles, and Trigun is an old favorite. If you like sexy but no sex ladies, then Noir is nice.
For action, I would definitely recommend Dredd. Not Judge Dredd, nope! Just Dredd, the newer one.
If drama is your thing, then The Client is fascinating. Not as good as the book of course, but still quite nice!
And for romance, um... Mulan? I guess? Or The Princess Bride, can't go wrong with that!
Any James Bond film will also float your goat, whether you are seeking car chases, pretty ladies, action, adventure, or a touch of mystery. If you'd like a little more car and a little less M, then the entire series of The Transporter will make for a lovely evening for you!
Edit: Oh, and if you are into the genre of "Movies that Everyone Hates Except Liela," try Doom with Karl Urban and Rosamund Pike. Anyone who played the games hated the movie. I was unable to play the games because they made me seasick, so I didn't have that particular problem. Neither the games nor the movie is anything like the book series. So just temporarily remove the games and books from your memory and watch the movie as an entire other story, and you might like it!
EDIT edit: OH! And Red. Definitely watch Red.
