What are some safe FREE tv show websites?

So as you probably have figured out, I’m a college student. This means very little access to the tv. I’ve tried free-tv-video-online.me and it used to work really well, but now it’s just a pain to get all these ads popping up (even with a pop up blocker) and having it load all the way just to find out there was a max time (usually like a couple hours or so) you could watch.

Any recommendations on sites that I really don’t have to sign up for, are safe, and I can watch Criminal Minds on? Or am I asking for the impossible?
