The Harry Potter franchise is one of the most beloved and successful franchises in the world. However, even the most die-hard fans of the series have to admit that there are some plot holes that can be difficult to overlook. Here are 10 of the biggest plot holes in the Harry Potter franchise.

1. Harry Should’ve Seen The Thestrals All Along: Thestrals are invisible to anyone who hasn’t seen death, but Harry had seen death before he ever saw the Thestrals. He should have been able to see them all along.

2. The Twins Must Have Overlooked Peter Pettigrew: In the books, Fred and George Weasley are portrayed as being incredibly observant and smart. However, they never noticed that Peter Pettigrew was living in their house for years.

3. Sirius Could’ve Hidden In Plain Sight With Polyjuice Potion: Sirius Black could have used Polyjuice Potion to disguise himself and hide in plain sight. This would have been much easier than the elaborate plan he used to escape from Azkaban.

4. The Professors Almost Led The Slytherin Students To The Troll: In the first book, the professors almost led the Slytherin students into the path of the troll. This could have been disastrous if it wasn’t for Harry and Ron’s quick thinking.

5. No One Ever Used The Truth Serum: In the books, there is a truth serum that could have been used to get information from people. However, it is never used in the books or movies.

6. Voldemort Should Have Killed Harry As A Baby: Voldemort had the chance to kill Harry as a baby, but he chose not to. This was a major plot hole, as it allowed Harry to grow up and eventually defeat Voldemort.

7. Harry Should Have Been Expelled For Using Magic Outside Of School: Harry used magic outside of school multiple times, but he was never punished for it. This was a major plot hole, as it would have been a much more interesting story if he had been expelled.

8. The Dursleys Should Have Been Punished For Abuse: The Dursleys were never punished for the abuse they inflicted on Harry. This was a major plot hole, as it would have been a much more interesting story if they had been punished for their actions.

9. Harry Should Have Been Suspicious Of Snape: Harry should have been suspicious of Snape from the beginning, as he had been a Death Eater and was not loyal to Dumbledore. This was a major plot hole, as it would have been a much more interesting story if Harry had been more suspicious of Snape.

10. Harry Should Have Been More Suspicious Of Draco Malfoy: Harry should have been more suspicious of Draco Malfoy, as he was a Death Eater and was not loyal to Dumbledore. This was a major plot hole, as it would have been a much more interesting story if Harry had been more suspicious of Draco.

These are just some of the biggest plot holes in the Harry Potter franchise. Despite these plot holes, the Harry Potter franchise is still one of the most beloved and successful franchises in the world.
