Arnold Schwarzenegger in Terminator GenisysTERMINATOR GENISYS

Following some requisite, necessary backstory, Terminator Genisys opens in 2029 Los Angeles, where resistance leader John Connor (Jason Clarke) transports fellow revolutionary Kyle Reese (Jai Courtney) to 1984, where he's to hopefully prevent global apocalypse and protect John's mother Sarah (Emilia Clarke) from a murderous robot (Arnold Schwarzenegger). Upon arriving, however, Kyle finds that Sarah doesn't need saving and the robot isn't murderous, so off they go to 2017, where the planet is still imperiled, and John Connor himself proves to be the source of the planet's eventual ruin. After one of these whisks through the decades, Kyle says, "Time travel makes my head hurt," and time-travel movies generally make my head hurt, too. But for a fifth installment in an increasingly confounding series, this particular time-travel movie is actually a fair bit of fun.

Mel Gibson in Edge of DarknessEDGE OF DARKNESS

For better and/or worse, Mel Gibson hasn't exactly vanished from the public eye since his last starring role on-screen, in 2002's Signs. Yet even if, like me, you've spent an inordinate amount of time bemoaning the Crazy Mel antics - both public and directorial - of recent years, you might find it hard to resist his turn in director Martin Campbell's Edge of Darkness: Gibson's back, and, happily, he's pissed. The movie is a frequently ludicrous and borderline incoherent revenge thriller, but its leading man, busting heads and blasting weaponry, is in excellent form, lending his bereaved-dad role considerable passion and emotional urgency. Between the mid-'80s and late-'90s, no one delivered anguished-and-wrathful acting better than Gibson. Ten-plus years later, there's still no one who does.

Sandra Bullock and Keanu Reeves in The Lake HouseTHE LAKE HOUSE

In The Lake House, Sandra Bullock plays Kate Forster, a Chicago doctor living in the glass-encased home of the movie's title. Upon abandoning her domicile for a move back to the city, Kate leaves a letter for the next tenant in the edifice's mailbox; the note is received by Keanu Reeves' architect Alex Winter, who responds, thus beginning a pen-pal relationship between the two. Based on their shared tastes, histories, and a fondness for melancholic gush, it's obvious the two are Meant for Each Other. But, unfortunately, a Happily Ever After doesn't appear in the offing, as there's a major hitch to their relationship: Kate lives in 2006, while Alex is firmly nestled in 2004.
