To allow people to avoid spoilers to endings they do not want to see in advance, I set the font colour to white when describing endings. Using your mouse, hold the left mouse key down and scroll over the invisible text you want to see.
Note that this is purely on the merit of the endings, not the shows as a whole. The Sopranos, Buffy, Angel, etc. are among shows that I liked as a series but didn't particularly like the final episode(s)
