GOOD THING: Barry Allen finally doing something to show himself worthy of the respect and praise everyone was giving him in The Flash: Reborn
BAD THING: Blink and you'll miss it, but Ollie and Dinah appear to be fighting a zombie Black Canary a.k.a. Dinah's mom. This is a great idea that deserves to be covered in full. I hope this is covered fully in a Blackest Night tie-in later. And that it is NOT written by Alan Kreisberg.
By the by, I just love how even in the midst of worldwide devastation, Barry STILL can't stop being a dick to Ollie.
