Confession. I was never a big fan of Schitt's Creek. I liked it without ever quite loving it. So I've come to Big Mistakes not knowing a lot about Dan Levy who co-stars and co-created this caper comedy thriller except that he is the son of comic legend Eugene Levy. In fact I know more about wunderkind co-creator Rachel Sennott, having just enjoyed her in I Love LA. She's not in it, though you can easily imagine her as the female lead.
