Whatever the case with no-nothing reviewers, this is an excellent movie that presents a unique storyline, characters you can actually care about, and a wonderful look and feel, complete with glorious '70s wardrobe, hair, cars, and style.
I think Flixster Super Reviewer Pamela De Graff said it best: "We've seen Lymelife's somber imputation in other movies about suburban values and relationships, Lymelife's is not a pensively warm-hearted slice of life, nor merely a bleakly cynical condemnation of the American dream. It's a reasoned, dryly tongue-in-cheek indictment of yuppie hypocrisies and contradictions."
And I liked the acting -- particularly by Keiran Culkin, who has grown up into a smarmy smart ass.
Overall, I think writing more would be redundant as I found De Graff's review to be spot on and more intelligently written than I can attempt here.
It's a complex whirlwind of grotesquery, tracing a young man's coming of age and his parents' separation, thick in the late-70s Long Island culture and in the horrific-as-shit explosions of infidelity, lost identity, and frustration. Everyone in the cast delivers exquisite performances, even in spite of a script that occasionally goes haywire.
