What does this phrase mean?
“C'est la vie.”
It literally means “That is life.” It's used to express acceptance of things as they are.
Watching isn't enough on its own.
Immersion is great, but you miss the words that matter, dictionaries break the flow, and nobody explains why a phrase means what it means. StreamTutor fixes that without taking you out of the show.
Three steps to a smarter binge.
Add it to Chrome

A teacher in your ear, not just subtitles.
Other tools show you a translation and leave you to it. StreamTutor pauses and walks you through the line the way a patient tutor would — then resumes the show.
