Does watching a TV series invalidate a missed fast, and must it be made up? Is inhaling food steam considered to break the fast?

Merely watching TV series does not invalidate the fast. However, if they contain forbidden content, it is not permissible to watch them, and the matter is more egregious if the person is fasting, as this contradicts the purpose of fasting, which is piety. Whoever watches them must repent and seek forgiveness. As for inhaling food steam, it does not invalidate the fast, even if done intentionally, according to the Shafi'is.
