I do not understand why the series is rated here badly, because the seventh season is not in Prime Free. Can the series for what? And it's not clear that not all in Prime series and seasons of the world can be free?
After rotating the whole thing, there are some then, so that you can find again a fee and others are free always something cool free. And just at Big Bang Theory are now already six seasons free to see.
If the provider therefore get bad reviews, they might put their series no longer in prime pure and all that would hurt.
