Box office winner

In the past 2 weeks, the release of the movie Harry Potter has broken a record. Making over 150 million in the first couple of days of it's release.
Many people have said that they should have stopped making Harry Potter movies a very long time ago, isint 7 movies enough? . The majority of people that watch these kind of movies are kids and young people, but not many like it very much, people exepected the seventh movie to be filmed at hogwarts but it ended up beeing filmed in a modern city, everyone wanted to see the magic spells and the magical places of hogwarts.
For many, they say that the first 3 were the best, but the rest had nothing to do with anything, they just started to get off topic.
At the start , Harry Potter movies were supposed to be based on Harry's life and how he is living threw this magical life. 7 years is enough, shoudint he have died 3 or 4 movies ago, for some reason he always ends up winning against the scariest monster. Good guys win and bad guys always lose, even tho they were the strongest. What happened to that scare on his forehead, why did they stop showing it.
In my opinion, i think that 3 or 4 movies are enough but why 7, i just think it's gets more boring each time, i just want to know how they come up with the new stuff. Starting out at hogwarts and ending up in a big city, everything changed.
