Making great TV is an incredibly difficult endeavor. There are countless variables to consider at all times, and even when you think you’ve done everything right — history often reveals otherwise.
Below is a list of 15 TV show mistakes that have stood the test of time. No matter how great these series undoubtedly were/are, it’s unlikely that fans will ever be able to look past these grievances .
Just how old is ‘Doctor Who’?

It’s a fair question to ask and depending on when you look, you’re likely to come up with several different answers. According to classic-era continuity, the Doctor is said to be between 500 to a few thousand years old. Yet when David Tennant takes the helm, he claims to only be 904.
Where did that picture come from?

I fancy myself a historian of The Simpsons ; there isn’t much that I don’t know or that gets by me. But even I couldn’t figure out how or why there’s a picture of Maggie hanging on the wall during the time that Marge is still very pregnant with her.
Did Dean just call Sam, “Jared”?

Back in Season 1 of CW’s Supernatural , Dean Winchester (Jensen Ackles) mistakenly refers to his brother, Sam, as ” Jared .” The actor who plays Sam Winchester is of course none other than Jared Padelecki.
‘The Crown’ gets the Queen’s coronation wrong.

Netflix’s The Crown has taken plenty of creative liberties over the years, but for something as monumental as the Queen’s coronation, you’d at least expect that to be accurate. The show claims that Queen Elizabeth II’s Silver Jubilee took place 25 years after the coronation when in reality it was 24 years.
Did Fox Mulder get married on ‘The X-Files’?

Back in Season 5 of The X-Files , FBI Agent Fox Mulder (David Duchovny) is seen wearing a wedding ring in the episode titled ” Travellers .” The only problem was that Fox Mulder had never been married at any point in time through the series.
How did Anna manage to call the police in ‘Coronation Street’?

When Anna finds Seb severely injured and lying on the street, she picks up her phone to call the police and EMS. The only problem is that somehow she was able to do this without unlocking her phone or dialing any buttons whatsoever.
Why can’t Penny remember her father’s name in ‘The Big Bang Theory’?

You’d think that remembering the name of your mother and father would be like second nature to a grown adult woman — but not Penny. When she first makes mention of her father, she refers to him as “Bob.” Later on, fans learn that his name is actually Wyatt.
The music in ‘Stranger Things’ is all wrong.

One of the greatest aspects of the show Stranger Things is that it’s steeped in ’80s nostalgia. However, in Season 2 (which takes place in 1984) the song ” There is a Light That Never Goes Out ” can be heard playing in the background — even though the track wasn’t released until 1986.
The infamous coffee cup in ‘Game Of Thrones’.

In the final season of HBO’s Game of Thrones , many fans accused the producers and writers of phoning it in. Seeing a plastic coffee cup in the middle of a pivotal strategy scene certainly didn’t help quell the descent.
Rob Lowe’s medals in ‘Wild Bill’ don’t belong to him — or any American for that matter.

In Wild Bill , Rob Lowe’s character, Chief Constable Bill Hixon, wears five medal ribbons : the Diamond Jubilee Medal, Golden Jubilee Medal, the Queen’s Police Medal, and Police Long Service and Good Conduct Medal. Not only are they in the incorrect order, but they are only given to British police officers.
Killer Bob was never supposed to be a character in ‘Twin Peaks’.

While they were filming, director David Lynch accidentally caught the face of crewmember Frank Silva in the mirror while Laura Palmer was screaming. He liked the effect so much that he created a brand new character, Killer Bob , and cast Silva in the role.
Do vampires breathe in ‘Buffy The Vampire Slayer’?

It’s a complicated question, to say the least. Back in Season 1, fans learn that vampires cannot breathe when Angel is unable to perform CPR. But if that’s the case, how are they also able to smoke, talk, and pant?
James Gandolfini didn’t mean to burn his hand in ‘The Sopranos’.
In Season 4 of The Sopranos , after Tony (James Gandolfini) kills Ralph, the scene was supposed to end with the mob boss laying his hands on the counter, gasping for air. In reality, Gandolfini accidentally placed his hand on top of a lit burner and yelled out in pain.
Was that the Smoke Monster in ‘Lost’?

In the very first episode of Lost , during the plane crash scene, a mysterious dark object rises straight up into the screen before the turbine blows. At first, fans thought this was an early manifestation of “The Smoke Monster” but in reality, it was nothing more than a CGI error.
What happened to Dr. Ross’ son on ‘ER’?

Dr. Ross was the young heartthrob doctor, played by George Clooney. Back in Season 1, Dr. Ross makes mention of the fact that he has a son on multiple occasions. Yet later on in the series, he claims to have no children.
