Travis Lytle’s review published on Letterboxd :
Steven Brill's "Without a Paddle" is not completely unwatchable, but the comedy is full of the kind of forced humor and ridiculous situations that sap any real enjoyment from the experience. An attempt at a mirthful adventure that finds three buddies seeking treasure in the wilderness of Oregon, the film has a few worthy laughs but does not amount to much in the final analysis.
After the death of a childhood friend, three pals, played by Dax Shepard, Matthew Lillard, and Seth Green, head to the wilds of the Northwest to continue their friend's quest to find riches in the forest. Misadventures abound, and the pals learn that friendship is the only thing of true value. The story is full of all sorts of mountain shenanigans, and, though every situation is scripted for maximum laughter, few achieve that.
The production is solid, and the cast develops chemistry as the film progresses. The jokes, emotions, and adventure beats all ring flat, however, and the film rarely genuinely appeals. "Without a Paddle" seems to have its heart in the right place, but it fails to stick any sort of comedic landing.
