I feel indifferent about Shinji. I think Shinji does do well in challenges, and when he actually talks, he can be entertaining. The problem is that, especially within the last week, he does absolutely nothing without being prompted to do so. Part of that is production's fault, the rest is on him. To be fair to Shinji I do think him not speaking English well is his biggest barrier, I can imagine if he was fluent he would be a lot more engaging.
The only one of the three that do anything unprompted is Tay. When prompted, Shinji is more entertaining than TJ, but he hasn't been prompted as much. When they monologue at the camera, Shinji is most entertaining, but he struggles to speak English so he doesn't do it as often as the other two. TJ can be entertaining occasionally. Tay just seethes.
I agree that Josie didn't "deserve" the win from the perspective of doing the absolute least, but they set up the game to incentivise doing nothing. Letty and Vance got punished for the first plotting that happened, and Letty was constantly punished for being the most entertaining. I think Josie accidentally chose the winning strategy.
Shinji has "played the game" from the start. He went into the show knowing that Josie was the winner, and he got to watch every entertaining person get hassled off the show. Shinji can be entertaining when he wants to be, but being entertaining puts you at a disadvantage because Jet's a retard.
If Jet didn't fuck everything up, the final three would be Brian, Jimmy, and Cole.
Of the three that remain: A TJ win can only happen if that's what the script they've written for him says, or if Shinji gives it to him. A Tay win can only happen if she steals it. A Shinji win can only happen if he's best at the game.
To me, the TJ win is undeserved, because either the producers or Shinji giving it to him shouldn't get the win. The Tay win is undeserved, because if being an asshole is the point it should have gone to Brian.
The only "fair" winner is Shinji, as far as I can figure. Not because he deserves it, but because the others don't.
