1.Bobby does care about PAa leaving Dallas - Pam leaving Dallas to spare Bobby and Christopher the pain of seeing her die I could just about accept, but Bobby effectively just shrugging his shoulders and letting her go and not being bothered to look for her stretched credibility too far.
2. Cliff Barnes kills his grandchildren - Cliff being so intent on harming the Ewings that he would risk the life of his only child and kill her unborn twins was ridiculous and totally out of character and was the final nail in the coffin for my enjoyment of TNT Dallas.
3. Michelle taking over Ewing Oil - Going from being "Little Miss Tight Skirt" to buying Ewing Oil? Totally ludricous.
4. Sue Ellen shooting but not killing JR - She fired 3 bullets into him at close range and he survived?
5. J.R marrying Cally - JR was ruthless in getting what he wanted so it's unimaginable that he would let someone like Cally trick him into marrying him. The real JR would have (1) paid her off, (2) tied her up in court and got the judge to side with him regarding her unborn child's custody, (3) got someone to threaten her or (4) set her up in some kind of sting operation so he could get rid of he and keep his child. In other words do anything other than marry her. He managed to get Lucy from Valene but he wasn't willing to do something similar for his own child?
6. Punk doesn't realise that Wyatt Haynes could be Wes Pamalee - Punk knew that Wyatt Haynes heard Jock "ranting and raving" revealing secrets of the Ewing family in the process and didn't occur to him that Haynes could have been Wes Pamalee or even to tell anyone about it until Bobby returns from South America and we're meant to believe this crap?
7. JR repeatedly reconciling with Sue Ellen - Really? By this time Sue Ellen was an old ex-drunk who hated him, happily would have sided with anyone to hurt him and she had already agreed that John Ross could stay at Southfork. Mandy was younger, more beautiful and loyal. She loved JR and was more innocent than the world-weary bitter and resentful Sue Ellen. In fact, Mandy was more or less everything Sue Ellen was when JR first married her. Further, Sue Ellen knew JR would never change his womanising ways and knew he would hurt her again to get what he wanted. She also knew as a recovering alcoholic she wasn't mentally strong enough to cope with J.R.'s bad behaviour. However, they both decided to ignore all this and get back together again.
8. Jordan Lee collaborates with Sheila Foley - As if Jordan would helped Sheila with her stupid scheme to masquerade as Bobby’s wife because he believed Sheila just wanted to make a speech criticizing OPEC. This man ran a successful independent oil company for decades and we are supposed to believe he would be so dumb as to believe this.
9. JR gets trapped in the asylum - This was a man who overthrew a foreign government, hired mercenaries who could have totally destabilised the Middle East and started an international war but he wouldn't have a more reliable plan to get out of an asylum?
10. Cally finds her inner Rembrandt - When Cally first started painting, her pictures were simple, naïve and childlike but had a certain charm. Then suddenly she inexplicably transforms herself into a brilliant portrait painter, producing an masterly painting of JR showing a high level of skill and sophistication that her earlier pictures gave no indication that it was within her capabilities.
