charmingly sentimental but ultimately pointless hommage to the sci-fi classics of yesteryear". Betsy Sharkey, in her review for the Los Angeles Times, felt that "there is attention to detail throughout this film, and it's clear that Goodwin loves those old sci-fi movies – maybe a little too much. While Alien Trespass stays true to the era and the genre, it forgets that its mission in this galaxy is not merely to pay tribute but to entertain". IGN mixed praise and complaint, saying, "Alien Trespass was clearly made with the intention to both emulate and satirize the classic B-movie sci-fi films of the 1950s – and not in a semi-serious Roland Emmerich kind of way, but in a careful replication of the era, complete with flying saucers, sub-par effects and some overly hammy acting.

And the visual effects, despite being created by CG to appear properly low-tech, feel enough like large plastic creatures and saucers on strings to blend seamlessly into the spirit of the piece. All in all, the design of the film is considerably more effective than its substance." In his review for The Boston Globe, Ty Burr felt that the film was superior to Monsters vs. Aliens, saying "There's more simple joy to be found here than in all of DreamWorks' 3-D extravaganza, though – a pleasure that comes from laughing at the movie and with it at the same time". Entertainment Weekly gave the film a "B+" rating and Lisa Schwarzbaum praised its "warm tone, along with the picture's bright, saturated, anti-CGI look, is a welcome respite from jokes, irony, and the postmodern malaise of know-it-all-ness". Gary Westfahl, a reviewer of science fiction, found this film and The Man from Earth (2007) to be overlooked gems of the genre. He hopes that they can both eventually be rediscovered. He found the film able to capture the "klutzy charm" and the true virtues of the
