I've completed it and yes Destiny is pretty terrible. I didn't care about the Story mode, I was only interested in the Crucible and Bungie were even able to ruin something they got so right in the beta not so long ago. The story mode has no story and it is awful; drive here, kill this wave, wait for Peter Dinklage to hack something, kill all enemies whilst he does that, drive more and shoot a boss till it dies. Repeat for every single level in the entire game.
