American Idol 8 p.m., Fox
Cue the confetti storm, the tears, and the filler. Tonight’s season finale will crown “your new American Idol,” even though you may not be watching because you may not care whether the winner is Candice Glover (left) or Kree Harrison. Rumored guests include Adam Lambert, Jennifer Hudson, and Jennifer Lopez, who is considering a return to the judge’s panel next season. Thursday night’s episode will be Randy Jackson’s last, after 12 seasons.
