The first full trailer for the fourth entry in the Transformers series is here after the first teaser during the Super Bowl and it kind of raises more questions than answers. Apparently the Transformers have fallen on incredibly hard times after the Battle of Chicago, with Optimus Prime becoming a rusted hulk of his former self. It kind of feels like if Captain America became a drunken hobo after The Avengers. Texas mechanic, Cade Yeager (Mark Wahlberg), finds him and jolts him back to life, but becomes the target of shady government agents and new Decepticons. Stil, it has Optimus punching Grimlock, a giant robotic T-Rex, in the face, so it may be worth watching just for that. The movie is out in June this summer and you can check out the trailer below.
