There's storied history of time travel movies, so you might be thinking "who needs one more?" You do. And this is the one you need. Admittedly not your traditional "time travel" movie in the same way that the classics of the genre are, but its weird angle on the concept is what Safety Not Guaranteed brings to the table.
To sum it up, Safety Not Guaranteed is an indie movie from the producers of Little Miss Sunshine that centres around reporters who answer a classified ad requesting a partner for a time travel adventure. Yes, t has the kind of slightly zany, kind of quirky humour you'd expect from an indie movie with this kind of premise, so hopefully you're OK with that. But it's also goes beyond just that, and really runs with the premise, to a place that's more interesting than you might expect. To say too much more risks ruining it. Basically, it's fun.
