>>90754989Season 3:Oliver became Ra's heir, it was a ploy, killed him
Season 4: Sara came back to life, Oliver became Green Arrow, Laurel got killed by Damien Dhark. Damien's plan was to nuke the world, they stopped all but one and redirected it to a place called Havenrock, killing people. Oliver became mayor
Season 5: Oliver has a new team of vigilantes and is facing against two villains: Prometheus, who wants to kill Oliver for something he did in season 1, and Vigilante, a, well, vigilante who has harsher methods than Oliver
Second half of season 3 and season 4 in general was shit. Season 5 has been an improvement and is actually good.
