One of the biggest sci-fi movies of the season, Oblivion, starring Tom Cruise, has a Friday release date and already, early reviews have begun to trickle in. We'll get to those in a minute, but have something way more exciting to share first: a 21-minute featurette/Oblivion trailer.

The new Oblivion trailer features tons of new footage (seriously: TONS) and more background information than we've previously been privy to. We're not going to go in-depth on this one because frankly, having watched the 21-minute Oblivion trailer, this reporter feels that the movie has been spoiled for him. The film looks great, so we'd suggest holding off if you can, but if you just have to know everything about the movie prior to the release date, scroll down for an embed of the trailer.

At the moment, Oblivion reviews on Rotten Tomatoes give the film an aggregate rating of 65 percent. It's worth noting, however, that there are only three Oblivion reviews in so far from Top Critics, and two of those reviews are positive, if not lukewarm. Here's a quote from Variety's Oblivion review:

"A moderately clever dystopian mindbender with a gratifying human pulse, despite some questionable narrative developments along the way."

The official plot synopsis for Oblivion:

"Following an alien invasion 60 years earlier which nearly destroyed the Earth, former Marine commander Jack Harper (Tom Cruise) is drone mechanic 49, one of the last few humans stationed on the planet. Jack lives in a tower standing thousands of feet above the Earth where he and his colleague Victoria (Andrea Riseborough) are part of an operation to clean up the remaining forces of the invasion and extract the planet's remaining resources.

Jack suffers from recurring dreams and flashbacks, featuring images of New York before the invasion and an unknown female. Assisting Jack in his cleanup work are weaponised 'drones', sophisticated airborne machines that scour the landscape for, and destroy, alien life forms."
