I'm using hydra but it's a pain in the neck because you always have to find a server that works because they don't always (I even had a server having the next episode rather than the one I was supposed to watch yesterday), and then you have to hope they have English CC because sometimes they don't (have English language, shocking but happens), or sometimes the CC doesn't work altogether, or there isn't such a feature either. This takes 5-15 minutes all the time per episode, and even if it's free, it's annoying as hell.

Edit: let me be more precise, I love hydra, I just am wondering if there's something that works better by having reliable CC for English learners/second language speakers
