The unlikely, but popular, pairing of former pro wrestler Dwayne “The Rock” Johnson and comedian Kevin Hart are at it again, this time as a pair of animated dogs in an enjoyable family trip to the movies. The two star in “DC League of Super-Pets,” a fun and safe for the whole family tale of how a group of enhanced pets come together to take on Lex Luthor (voiced by Marc Maron) and his evil pet experiment, Lulu (voiced by Kate McKinnon) — both bent on world domination.
