Nothing makes sense, and as a result nothing matters. People accuse everyone and everything, but the core reason is that none of the current storylines on the main show make any sense.
The big storyline going into TLC revolves around Sheamus is going to show Reigns he cannot beat him. He talked about this on RAW for three hours. However, within the first 30 mins of that RAW Roman Reigns pinned Sheamus clean. Why would anyone care about TLC after that happened on RAW. The question you posed to fans was answered before you even asked it.
That is the main event... and going through the card for TLC each and every match has similar issues. Regardless of the talent involved or not involved due to injuries the problems are the same. Nothing matters because it makes no sense. You could have the two stop stars in the company face each other, and it would not matter as the writing makes no sense. They cannot build a compelling story when they cannot even follow simple storytelling logic. It is attritious.
NXT on the other hand makes logical sense, and you can get invested in storyline.
