Dwight Schrute said in The Office that the reason he joined Second Life was because his first life was so great he wanted another one... 

If that's not enough to put you off spending more time on the web, then maybe this keystroke-driven chiller from the Blumhouse shingle will do the trick - a standalone sequel to 2015's paranoia primer. Some of the producers of Get Out are behind ...Dark Web and while not in the same league as that landmark, Unfriended is shaping up as a decent anthology franchise.
