If you still care enough about the plot to not want to have things spoiled for you, you might as well keep going. I think a lot of the plot points you seemed to really dislike get tied up soon. The last few episodes have a plot that is more straightforward and has less to do with stuff to screw with you head. That isn't to say everything you dislike is going away, though.
