The issue with Destiny is that its best experiences are hidden away many hours after actually beating its story mode and soft level 20 cap.
The nightfalls and raids (especially on hardmode) can't be accessed or even completed until you are max level 30 (now 31-32 for Crota's End raid), or very close. Hard VoG raid is one of the most amazing experiences I've had in an FPS ever. The co-operation and skill required of all 6 players makes it such a challenge to beat. The rewards are also some of the best and very frequent, unlike any other activity in the game.
It's just a shame that most people who hate Destiny are doing so without ever having experienced some of its most unique, best and rewarding content. To be honest I don't even blame them for it because Destiny as an experience changes completely once you reach the highest echelon. Until then it is a very grindy and monotonous experience with a stingy reward system. And therein lies its biggest fault - it is an amazing experience, but you have to work through the monotony to get to that experience.
