A lot of people are quoting from the EFF, which I caution with regards to the TPP. They had a shambles of an AMA last year on the TPP where they failed to argue their points very substantively at all:

It's also worth noting that they were invited to be part of the TPP negotiation process but declined. The agreement itself is not that difficult to read. It's meant to be used as a practical functional document, after all. The one thing that is a little tricky is that carveouts and exceptions to one mechanism or another may be listed in a separate chapter.
Then again maybe you did read it that way and still found it not that bad. I admit I didn't read it myself, but then again I'm from Europe so it's not my agreement to check. Still I have some faith in the EFF and other organisations which did read it and found it a dangerous agreement. And I really think it's a good thing that it's now harder to negotiate trade agreements in secret. It doesn't matter what the traditional way to negotiate these was, they have a big impact on the countries that implement them, and people deserve more than just a (representative) YES/NO to a huge number of potentially life-changing provisions at once.
