The title of the film is quite appropriate as the plot is centered on our hero's Harold (a young Korean American investment banker played by John Cho) and Kumar (an Indian American medical school candidate played by Kal Penn) attempting to get to White Castle for a late night craving.
Just like the burgers, it's not for everyone. You have to "get it." To put it bluntly, Harold and Kumar is a "stoner comedy" in league with such films as "Half Baked" or "PCU". As a member of this class of film it is truly exceptional and funny. What makes the film so good in this capacity is that it understands its sophomoric nature and plays to it rather than trying to please the masses.
The excellent writing (credited to Jon Hurwitz & Hayden Schlossberg) lends itself to the extreme but the jokes work and the actors take the material and themselves non too seriously. This is very evident with the hilarious cameo from Neil Patrick Harris who in this film is a far cry from "Doogie Howser M.D."
There are some moments where it does go to far into the realm of weirdness (at one point Harold and Kumar ride a cheetah through the woods) The writers however know this is a ridiculous scenario and thus is garners laughs. Harold: [riding the cheetah] "Dude, am I really high, or is this actually working?" Kumar: "Both."
As Harold and Kumar drive around the state of New Jersey in search of the White Castle they meet a cast of interesting characters who have some of the best lines in the film. One of the more memorable characters is a dubbed "Freakshow" the Jesus loving, devil hatin' pulsating boil necked tow truck driver who invites the pair to "Go on inside, boys, and make yourselves at home. You can rest up, get something to drink, **** my wife, whatever you want. Just don't do anything Jesus wouldn't!" Kumar: (incredulous) "Did he just say we could **** his wife?"
The easily offended should steer well clear of this film as it earns its R rating through extreme political incorrectness, heavy comedic drug use, and nudity. If however this is your type of humor, this is your type of movie and one of the best of its genre. Now I'm craving a 10 sack.
