"Loser," which is directed by Amy Heckerling (whose "Clueless" is about a young woman whose sophisticated character is diametrically opposite Paul's), may be predictable and overly sweet, but after a steady stream of mostly good movies that try to outdo one another in vulgarity ("American Pie," "South Park," "Me, Myself and Irene") the picture is a welcome change as mid-summer approaches--so long as we don't get a steady stream of cuddly little tales that could as soon pass muster on TV shows like "Friends." The screenplay, also by Ms. Heckerling, does not feature a whole lot of bon mots, but in the tradition of the cinema the villain--in this case a handsome, smart, but charmingly sarcastic professor--gets the best lines.

By way of comparison, Jim Carrey's character, Charles, finds out in "Me, Myself and Irene" that being nice is not all that it's cracked up to be. If you're congenial, you'll be taken advantage of, your sweetness all the more tempting to those who'd eat you for breakfast. In this case, Paul's warm and geeky hat may be suitable for Fargo, North Dakota but is as out of place in the Big Apple as his nerdy haircut. When he meets the adorable Dora Diamond (Mena Suvari) who sits next to him in European Lit., he's hooked, but Dora has eyes only for her comely professor, Edward Alcott (Greg Kinnear), who sometimes treats her almost as badly as Paul is treated by his rich, snotty, and altogether too hip roommates Adam (Zak Orth), Chris (Tom Sadoski) and Noah (Jimmi Simpson). When Paul eventually takes up residence in a veterinary hospital, his fair-weather pals talk him into letting them use the facility for a bash at which they pass out the infamous date-rape pills to naive and trusting co-eds. The greater part of the film deals with Paul's uphill battle to prove that you can be decent without being a doormat.

Jason Biggs, well cast here (he's the fella who last year mistook an apple pie for a sexy woman), turns in a fine performance as the guy who never loses his congeniality but does become a bit stonier in his ways under the pressures of his first year at college while Mena Suvari, who could pass for a young Liza Minelli, is amiable enough. Greg Kinnear as the elitist professor stands out: he's the sort who would have the populists, especially the young people, in the audience hissing, but I like the guy. He stands firm in his championship of the best and brightest and is appropriately ticked off when he discovers that virtually nobody in his 160- member lecture class has read the Kafka assignment or has understood the text enough to deal with the principal theme. When he visits a museum with his co-ed, he appropriate patronizes her for thinking that there is nothing particularly more beautiful about a Van Gogh or Greek column than there is in, say, some Christmas decorations.

"Loser" is a date movie suitable for dates who can appreciate "American Pie" as much as I do but still like to indulge themselves in a confection which proves that a kid from the sticks can make it in New York without giving up his decency.
