I can't think of a job that I have had that was perfectly described in the job posting. Something is always different. As far as bad jobs, there is always some opportunity. If there is free time, work on something else or take online classes if the company would own anything you work on. If you are stuck doing busy work, automate. It is also fair to jump ship. Not every opportunity is worth it. I would say, before you go, try to learn what happened to make this environment so bad. It will be useful later. Good luck.
