2015 · 5 Seasons · The CW · Comedy, Crime, Supernatural
iZombie takes the zombie genre somewhere it's never been, blending procedural crime-solving with comedy, romance, and surprisingly smart worldbuilding. Rose McIver is a revelation, and the show's first three seasons are as fun as television gets. The final two seasons can't match that peak, but the ride is worth taking.
2003 · 9 Seasons · The WB / The CW · Drama
One Tree Hill is a sprawling teen drama that's at its best when it focuses on the complicated relationships at its core and at its worst when it chases absurd plot twists for shock value. The first four seasons build something special, and the time jump reinvents the show with enough success to justify the long haul.
2012 · 8 Seasons · The CW · Superhero / Action / Drama
Arrow kicked off an entire TV universe and delivered some genuinely great seasons of superhero television, but its inconsistent quality across eight seasons means you'll need patience to push through the rougher patches.
2007 · 6 Seasons · The CW · Drama
A stylish, addictive teen soap that defined a generation's fashion and pop culture sensibility, even as its plotting became increasingly absurd and its characters increasingly difficult to root for.
