I agreed with the OP, but I found that once I perservered, the game really opened up. I know, 'a game that takes a while to get good isn't a good game' but I feel that Dragon Age is an exception to that rule - it's more of a slow burner than 'bad' at the beginning, and it fouls the pacing up a bit but it's not so bad. My personal favourite origin is the female city elf, which is really, really well done, and I think I was a bit disappointed that it didn't play a more vital role in my story, but oh well.
Oh, I've tangented. *rerails*
What I mean by slow burning in this case is that in the beginning, when you don't have all your party, and those that do don't necessarily trust you, your own character feels quite limited. However, once you start getting a full party and personal quests, the game just feels so much more complete, with the way they banter at each other, or will voice concern/support for your decisions and so on - so that it actually begins to feel like more of a personal story, with the warden associating with companions that are coherent characters in their own right (the best thing about the characters is the ditching of the morality system from previous bioware efforts. Now no longer will a character be blindly lightside/darkside/neutral, but actually driven by their own ideologies - Morrigan's darwinistic pragmatism, Sten's Qun, Shale's hatred of pigeons, etc.
Oh wow, derailing hard here. Just a second.
OK, to wrap my incoherence off (it's 7am, please forgive me!) what I mean is that I think the game can be ofputting at first because it takes a while to get going, but once it does I find it a genuinely compelling story, and I like how I my actions have way more freedom than say, Shepards in Mass Effect, because it makes me feel like more of an active participant than an actor with a few lines of dialogue. If you can, push into the game, unlock the personal quests, and see what you think of it then. If you still don't like it, or it's too much to ask, then fair enough.
