Independence Day (often "ID4"). This movie is kinda old, but its special effects quality and story quality is not bad at all. As a matter of fact I loved it!! My childhood movie!!
Dawn of The Dead Remake: I liked it, though I almost vomitted in the theatre.. But after seeing the DVD's "making of", it ain't that bad!
Running Scared: One of the most underrated movies of all time.
300: Good, but been there, done that.
Shaun of The Dead: After watching Dawn of The Dead, I got really hooked on zombies and I watched this and laughed my ass off...
