Josh Wilding reviewed The SpongeBob Movie: Sponge on the Run for ComicBookMovie.com and gave it 3/5 stars. Note his comments on Keanu as Sage below.
The same can be said about the terrific voice cast, with Tom Kenny (SpongeBob SquarePants), Bill Fagerbakke (Patrick Star), Rodger Bumpass (Squidward), Clancy Brown (Mr. Krabs), Carolyn Lawrence (Sandy Cheeks), and the rest of the returning favourites on top form. Matt Berry’s take on King Poseidon is fine, while Awkwafina is extremely entertaining as the robotic Otto. However, the true scene stealer has to be Keanu Reeves as Sage, a bizarre addition to Sponge on the Run, but one you’ll get an endless amount of enjoyment from. (Bolding mine)
