From the sound of it, the beer is just young. IMO, it's hard to tell what a beer is going to really be like when taking a sample from the fermenter. Personally, I would never let any hops from the boil go into the fermenter.
I always sip on a little bit when I'm bottling, and it never resembles the final product.
If it's still in the fermenter, I would say go ahead and dry hop it for a week, then get it bottled and let it condition for at least 3 weeks. How often do you use Chinook? I'm wondering if you just don't like that hop. I've heard of people complaining about how harsh of a Hop it is. I personally love it.
Anyhow, don't give up on it.
