Arrow: 10 Most Disappointing Episodes Ever
5. Season 3 Episode 14: The Return
Slade Wilson, A.K.A. Deathstroke, was one of the best aspects of the first two seasons. Manu Bennet plays this lost and hateful man with visceral charisma. His turn to madness in season 2 remains one of the shows' best storylines. When he was announced to return in the underwhelming season 3, fans were hopeful.
The showrunners must have something against the fans of this show, because this episode is amazingly, completely average. Slade has around 5 minutes of screen time, in which he repeats the same threats as last season, and then gets beaten up by Thea in a 20 second fight scene. Manu gets barely anything to chew on here; it's bottom of the barrel fan service at its worst.
This episode could've been so much more. It speaks its superfluous nature, when you could entirely remove it from the show, and absolutely nothing would change.
