EDIT: To wannabecomedeat: Don't necessarily be so swift to disregard synthetic reverb. Sure, recording natural reverb's almost always better, but that's not always feasible. Synthetic reverb shouldn't be SO useless as you've described. Just to make sure, you do realize that reflective-type effects (reverb, chorus, delay, echo) are meant to be put on a send, right? If it's still too fake for you even so, you might look into a convolution style reverb. Those are more realistic, if way more system intensive.
