I know a lot of people hate dan brown books but honestly I don't get why people need to trash talk them. They are no masterpieces but they are a fun read that gets you invested. Obviously fictional and no way realistic but just great to actually stay motivated to read. It doesn't need to be serious and deep reading all the time.
And then shitting on what he writes about?! Yeah if you don't like it move on and find a different author with a different style and genre if you think he writes nonsense. I think he actually does a lot of research for his books since they have a historical core even if it's embellished with lots of made up conspiracies. But then again if you can differentiate between reality and fiction and go with the flow it's a pleasurable read in my opinion.
Everyone should be allowed to read what they want and to not fear what others may say. That's true for anything really. From high fantasy to romance novels. Reading is reading and should be always looked upon as a good thing.
