Sooooo he's actually this month's showcase...alright then, here are my thoughts on Rhett. He's not a very likeable character, that's true, but if you ask me, that's due to blandness more than anything else. Yeah, he was rude to the Gang of Five and fibbed to everyone, but why does that make him any worse than the also blandly-mean bullies from III? As a one-note liar/jerk of a kid whose actions caused nothing more than annoyance, I wouldn't even say he's worthy of the villain character showcase.
It always looked to me like Rhett was vilified in the LBT fandom far more than he ever was in the show, which kind of baffles me. Is it because he came between Littlefoot and Ali or something like that? I guess I just must not feel as strongly about Littlefoot+Ali as the rest of you do, though I do agree Ali was introduced as a Littlefoot love interest and is the only character shown in the series that Littlefoot could reasonably end up with. Maybe I'm just not much of a shipper in general, because I can probably count all the ships I care about on one hand.
Call me crazy, but I always thought the Brave Longneck Scheme episode was fun. The scene where the gang rehearses their plan always had me laughing, especially with how giggly everyone is the first run-through. And Rhett got what was coming to him when Chomper came tearing out of the bushes at him!
