Jury speeches typically don't do anything for me... Most of the time it'll either make me think someone's annoying or I just find these speeches kinda boring. And that's with both the jury & the finalists.
Out of the ones I saw here, Erik's speech in Samoa was pretty great even though I would've slightly preferred to see Russell win the season (not that the speech definitely influenced anything at all).
Also, Phillip during the entire FTC of Redemption Island was excellent though.
