SAFETY NOT GUARANTEED

Fascinating, "one of a kind" script written by Derek Connolly,  intelligently directed by Colin Trevorrow, and flawlessly acted by a wonderful cast featuring Aubrey Plaza, Jake M. Johnson, Mark Duplass, and Karan Soni.  No high-tech effects messing up the unfolding of the plot which is a charming blend of sci-fi, mystery, and romance.   Three of the main characters (two interns and one Reporter) are on an investigative assignment from a Seattle magazine to find the person who placed an ad a newspaper inviting anyone interested to apply for the opportunity to travel back in time with him in the time machine he has invented (the ad warns, "Safety Not Guaranteed.")   Questions: Has he really invented such a machine? Are there really people following him, or is he just paranoid?  It's worth the time to see this entertaining film!
