This could have been a really good movie, but it wore out its one-joke theme - straight guys who love nothing better than masturbating together while watching porn - about the third time it played out. That may be a powerful and persistent fantasy and an infallible source of amusement for lots of gay men, but it's not for me, and watching it in a movie gets old very fast. It wasn't even remotely believable the first time it happened, and it got less believable every time.
The second recurring theme has one man stripping completely naked and standing still for another, fully clothed man to ogle. Each of the five main characters did it once each, with another of the five (two, in one instance) as the clothed ogler. Was that supposed to be funny too, or was it just an extremely clumsy way to get as much full frontal (but as sterile as a nun) nudity as possible into the movie? So the movie is almost unbearably contrived, stupid and unfunny. It has two redeeming strengths, though.
Three of the main cast members are genuine Southerners who talk with real Southern accents, not the Hollywood fake-Southern accents non-Southern actors always affect (even Meryl Streep can't get it right) in movies. Non-Southerners must not be able to tell the difference, but I can, and as a long-time transplant to the North, hearing people who talk like me on screen warms my heart and points out how very, very rarely it happens. Even Southern actors almost never use their native accents in movies, which is sad.
The movie's other strength is the cast, particularly Derek Villanueva and Dylan Vox, who shine (Jacob Newton, though sort of cute, is a little weak as the lead). I wish someone would remake Longhorns with the same cast but as a serious movie, not a very lame, very unfunny comedy.
