What's your least favorite film franchise that you've seen every movie in?

Or the vast majority of the movies in, if every movie is too onerous a limitation. As a follow up, why did you stick with the franchise? Did it get bad suddenly? Or do you have a relationship with the source material? I'm curious about what our modern relationship to "franchises" is? And why we keep seeing movies we don't like? via /r/movies https://ift.tt/2pWRF3l
