These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
On the British version, any time the contestants encourage their new friends.
Hype Backlash: Deal or No Deal could be the posterboy for this in the United States. It being so aggressively promoted by NBC and aired so frequently, without delivering the potential big wins it boasted, led to its quick downfall; people just got tired of it.
Misplaced Nationalism: The American version was disparaged simply because "They "Copied" the British." Problem is, DOND is a Dutch format.
Padding: The NBC run might as well have been Padding: The Game Show. Seriously, did it really have to take 44 minutes to pick out 12 cases?! The syndicated run improved in this department with a more fast-paced game.
Note: That was for an episode with two contestants (some countries only have one at a time). It actually took 1:40 for the first contestant, and just 1:05 for the second.
The show seems to actually speed up the game and avoid the trope when the contestant has knocked out all the big money amounts off the board. Once the contestant isn't going to win a big amount of money, the game suddenly starts to pick up the pace to get rid of the contestant.
The 200th episode special completely averted the trope by rapid picking each case (Howie picked each case and then the contestant would pick cases on their own after a certain amount were left) and then knocking all the money amounts chosen at the same time instead of one by one. No phone calls to the Banker were ever made, opting to show the offer right away and giving the contestant 20 seconds to make a decision. The whole purpose behind the change was, of course, a stunt — if the show gave away at least $1,000,000 that night, the Banker would dive into a cake made to celebrate the 200th episode; if not, Howie would jump into the cake instead. The goal wasn't reached.
Proof if proof were needed that game had a lot padding is that, on the U.S. version, recordings of a single player's game could take upwards of 8 hours. 8 hours. For one contestant. For a 45 minute show.
Surprisingly Improved Sequel: Removing the family members, whose basic purpose on the NBC version was just to shout, "You're a risk taker! No deal!" and give bad advice, made the game run a lot more smoothly.
The syndicated run took a great element of the British one (prospective contestants holding the 22 cases) and took away the one thing about it that makes the Brit take on the format great. On the British version, those holding the boxes stay on the show until they're chosen by the producers — which may be days, weeks or even months — and in the meantime the group becomes like a family (as can be seen in virtually any episode); in the syndicated version, however, each week was self-contained...until the very end, at which point They Just Didn't Care anymore and taped four weeks with the same group which then aired Out of Order.
The Dutch original's 2011 series. They dropped the "block versus block" part of the quiz, and instead the top player from each block comes down and plays against another player in a survey question, with the closest answer going through. The third round works a bit like the British game show Number 1, and it works fine, but the greatest atrocity committed comes in the briefcase game. They've dropped having the players from the winning block open the briefcases and make predictions for cash, and now the models themselves have been given the task. A major sting in the tail comes when you realize that almost all the temptations, a major part of the original game, have been removed.
They Just Didn't Care: The syndicated run, whose main draw was having each week be self-contained, used the same gallery of 22 contestants for four weeks near the end of the run — which then got aired Out of Order.
Choking from the pressure cost two people in the US version the top prize when they caved to the banker's offer. It would have been alright... had both times not been for twice and then thrice the normal $1,000,000. In fact, you could tell when a playthrough was screwed if the banker put up a six-figure offer and the words "college fund" were spoken by a family-supporting contestant. Heartwarming that they look out for their family, but almost always a tell that they are not going to stay in the game.
