First recommendation, make beer that YOU enjoy. The reward is that much more sweet.
Second, the above posts are certainly good places to start, but you might do better by posting your whole recipe including starting and finishing gravities, etc. If you had poor efficiency resulting in a lower-than expected OG, then you will likely end up a lower-flavored (watery) beer if your recipe did not account for the low FG with specialty malts.
Also, if you brewed a beer two weeks ago it is way too soon to be forming opinions about it. Is it even bottled?
Hope your next batch goes better!
