Does PR agency environement suck or NOT?

I worked in the PR agency environment for quite sometime and have found that this industry is quite tire some, FALSE/PRETENGIOUS/FAKE and whatever you wanna call it. I did not enjoy the agency environment, however i do believe that PR can add value to any business, but my problem is that PR agencies are ripping off companies and making you feel like you selling your soul to the devil. this is becuase you always have to suck up to someone, which is not cool. Lets not talk about billing, cause I know of PR agencies that bills for the last thing.

I would like to know from PR practioners what their take is on the agency environment.
