I couldn't take the fallen series at all. I finished the first and it was not interesting to compel me to read the next 7,000 books in the series lol
And as for requiem, I couldn't NOT read it, like was the case with Mockingjay, but I was slightly disappointed with the former while I literally skimmed through the latter. There's SO many series I haven't finished and the one that stands out HAS TO BE PRETTY FUCKING LITTLE FUCKING LIARS. SARA SHEPARD NEVER SEEMS TO WANT TO END THE FREAKING SERIES THERE'S LIKE A ZILLION BOOKS IN THERE MAN AND A HAS CHANGED SO MANY TIMES I'VE HONESTLY LOST COUNT, others being mortal instruments, Vampire academy, Vampire diaries, and-wait for it- HARRY POTTER.
