I to am new to all this, and Mike is right, "Ask your priest" is the bestest answer.
Now mine (prideful and dreadful creature that I am): ask your priest
but prior to doing so, maybe we can reason together.
What is the purpose of Great Lent your real question?
If not, don't bother reading on.
If so, then Great Lent affords us the opportunity to "learn something new" AND draw closer to God.
If that is the case, do movies and TV allow such or distract us? And for such a short period of time too, we, as a church, can lengthen our time and desire to seek, know and try to become one in His presence! All of us, for a few simple days, a moment at a time!
So now, go ask your priest.
