For a game that's winding down, they're really throwing a lot of stuff in that has to be televised.
Sunday's episode is really a combination of the usual Sunday and Tuesday format, with the main events being the nominations AND veto competition. Yet they also must fit in the luxury competition, as it's another piece of product placement. They can't give away a prize package centered around a movie that opens next week without showing it.
Plus, the producers cannot resist showing Sheila and Adam shackled together. Yes, that can be a short segment, but it's too comical for them not to include it.
Add in the campaigning, and that is a lot of material for a sixty-minute episode.
Tuesday's episode is really Wednesday's a day early, although there's some talk that it will not be live. It will start with the veto meeting, followed by some campaigning, then move on to the eviction and the beginning of the first part of the final HOH competition. Even if it's not a live show, though, I can't see them NOT showing Natalie's entrance into the jury house. I beg, beg, beg the producers to let us see the reactions of James, Chelsia, and Matt when she walks in the house.
There's also some late-breaking news about the finale. Currently, it's scheduled for Sunday, April 27, but the networks are negotiating a Democratic debate for that evening. If that does occur, it was said on House Calls that they will move the finale to Tuesday, April 29.
No matter which day it airs, there's still two episodes of material that needs to be squeezed into the finale. Correct me if I'm wrong, but in previous seasons the final two HOH competitions were shown in one final "normal" episode before the last show. Now they must include this material before they can even get to the cast reunion and final vote.
I think the way they're cramming this all together is an indication that this season is considered a ratings and personality failure...which we've all been saying the entire season.
