Your Highness (2011) — A clumsy, clueless wannabe knight (Danny McBride) helps his heroic, handsome older brother (James Franco) rescue a dimwitted princess (Zooey Deschanel) from an evil wizard (Justin Theroux). A pretty swordfighting ace (Natalie Portman) helps. Stupid, aggressively unfunny, nasty, clumsily plotted, and a colossal waste of talent, this stoner medieval tale is 2011’s worst movie, so far. Whatever happened to David Gordon Green, the director of such Southern-tinted minor masterpieces as Undertow and George Washington? R; 102 minutes. Grade: D- (Also on Blu-ray)

Super (2010) — A lonely short-order cook (Rainn Wilson) loses his recovering addict wife (Liv Tyler) to a local druglord (Kevin Bacon) and reacts like anyone else would: He has a supernatural encounter with The Holy Avenger (Nathan Fillion), cobbles together a homemade superhero costume, uses a wrench to beat the snot out of bad guys, including those who merely butt in line, and along the way picks up an excitable motormouth sidekick (Ellen Page). Somewhat reminiscent of Kick-Ass, Super is an excessively violent, darkly comic, deeply bizarre tale from one-time Troma Entertainment director James Gunn. It’s all a bit too surreal to be as subversive as it wants to be. R; 96 minutes. Grade: C+ (Also on Blu-ray)

Mars Needs Moms (2011) — The motion capture animation is impressive, as are voice performances by the likes of Joan Cusack and Dan Fogler, but the simple story, based on a book by Berkeley Breathed and directed by Simon Wells (The Prince of Egypt) is really stretched thin. The visuals, and some of the dialogue, make references to the psychedelic ’60s, and, oddly enough, the male Martians are fun-loving, sensitive party dudes, while the majority of the female Martians are mean-spirited automatons. And the bigwig Martian could be E.T.’s really mean grandma. Grade: C (Also on Blu-ray)

Paul (2011) — Sci-fi geeks played by regular collaborators Simon Pegg and Nick Frost, on a road trip to Comic-Con, encounter a nasty, dope-smoking slacker alien (voiced by Seth Rogen). Directed by Greg Mottola (Superbad), the stoner comedy also features Kristen Wiig and Jason Bateman. (Also on Blu-ray)
