Divergent series relation to Maze Runner series

So I am now on the third and final book in the "Divergent" series by Veronica Roth, the book "Allegiant". Now I noticed this in the first book, but the relation really came out in the second and third books. This series is very similar to "The Maze Runner" series by James Dashner. Now a movie is coming out soon for the "Maze Runner" series and a movie just came out for the "Divergent" series so I will try to leave all spoilers out, but there might be slight hints to what happens later on.

So the reasons these books are very similar are abundant. To start they are both post-apocalyptic books, but then again about every other young adult book now is. Veronica Roth's story takes place in a walled in, half burned out, grim looking Chicago(One of the best city's ever). While Dashner's is in a maze, so not much similar there. There are multiple small similarities through each series throughout their plots and themes. But the main huge similarity is the plot of each book. Now if you didn't already know "The Maze Runner" is about way more than just a maze, I mean seriously way more. It's one of those twists/enlightenments that almost make the first book irrelevant, it remains relevant though and was the bases of the themes and whole drive of the story. Now Roth's plot is very strikingly similar. Roth's series like Dashner's first takes place in a both physically and mentally cut-off world, they have no idea why they are there they just are. They solve the problem within the their own seclusion and yay everything's happy and normal now! Nope the opposite happens, they then find out about the world they live in really really sucks. Then a whole massive plot happens diminishing the old one. If you haven't read either of these books or just one I have two words for you, read them.
