Mobster John Alite, who testified against John “Junior’ Gotti in 2009, is giving the movie about John Gotti Sr. a horrible review.

The film “Gotti,’’ with John Travolta in the title role, features “bad acting’’ and “horrible writing,’’ Alite told The Post. He complained that a “good-looking actor plays [Gotti], who [was] an awkward-looking gorilla.’’

“Street guys around the world . . . don’t give two f–ks about that bulls–t name that destroyed the mob,” he added. “He was never a legit street guy and all of us real killers [and] gangsters know this.’’
