It's not unfinished. It might not have the amount of content YOU want, and sure it has things that can be improved on, but name one game that was perfect at launch and didn't need a patch, DLC and nobody complained. I like it and have received my value for money - even if the end-game is lacking. I've played many other games that I didn't like that got critical acclaim but I recognise perhaps I wasn't the right demographic or my expectations were wrong. So you move on, not try and make the game revolve around you and your wants - especially when they might be at odds with many others. At the end of the day it's Bungie's game and if I don't like the direction they take, or the amount of support they provide I'll just play something else.
