I've had a similar experience. So much hype about each new place I've joined only to find the same levels of corporate political crap. What kills me is the lack of care about the quality of the product. "Good enough" is never actually good enough for me and when you are the only one (or at least in an extreme minority) in the entire company that cares about that, it's incredibly demotivating.
I've recently joined a very early stage startup at a pretty high level. I'm in charge of an entire class of product (mobile native apps) and it's been the best experience of my career so far. It's stressful and tough but I'm 100% in charge so I can care as deeply as I want and it's up to me to make it work. Very rewarding vs the typical Corporate slag.
