There's a little bit of everything this week. From dark mermaids to Scooby-Doo crossovers with CW staples, prepare to start checking some stuff off your bucket list.

Freeform's new series Siren makes its debut this week, while Supernatural crosses over with Scooby-Doo for what promises to be one heck of a meta episode (loaded with Dean hitting on Daphne, we'll assume). It's not exactly genre, but FX's acclaimed thriller The Americans is also back this week. SYFY has a new episode of the Superman prequel Krypton, as well as some political fantasy intrigue on The Magicians.

Rounding out the week, there are also new installments of The Walking Dead, iZombie, Black Lightning, Last Man on Earth, and a whole lot more. Check out our full rundown below and let us know what you'll be watching.
