“Ripped” (** out of four) was a chronically dumb marijuana comedy about two stoners (Russell Peters and Faizon Love) who smoke biologically enhanced marijuana developed by the C.I.A. in 1986 who then suddenly awake in the year 2016 when marijuana is beginning to get legalized and attempt to sort out all of the many changes that have taken place in the past 30 years. Occasionally funny but more often one-note and silly. Cheech and Chong and also Dave Chappelle offered a much more potent hit of the same material 20 and 30 years ago.
