The Day of the Triffids, 1981. Zero Stars.
It's not even fair that I even mention the possibility of stars. My boyfriend Tim and I rented this TV miniseries, and it was so frustratingly boring that we stopped watching after the first episode and returned it.
So all I can say is, it's so boring that I couldn't watch it. And that's saying something, because even if something's terrible, my need for closure keeps me watching movies and such until the bitter end.
