I kinda like it. Actually, I thought Titus was his longest play, but no matter. For pure bad guy, RIII is just terrific. You got to love a villain who says,
Conscience is but a word that cowards use, devised at first to keep the strong in awe. Our strong arms be our conscience, swords our law.
Titus isn't even close. It's R3 followed by Hamlet. The latter however justifies its length.
