Let me tell you...
What I didn't like: How Rancor was wasted as a character. How it's difficult to tell who's speaking. How we're told and not shown things. How Tirek was written. How Luna was written. (the Pony POV Series is a Luna's a Prick fanfic) How we're suppose to like the unlikeable characters. How we're suppose to buy the draconequi aren't evil. How Alex turned Dark World Twilight into a Mary Sue wish fulfillment fanfic. How we'll never get to know more about D___t. How Havoc/Entropy/Strife never get any comeuppance. How things are never explained. How the stupid fanboys keep objecting to my complaints. How so many character are never described. How Rainbow Dash doesn't have many awesome moments. How boring and filler-ey the Shining Armor Arc was. How boring and filler-ey Dark World was. Those are all the ones off the top of my head.
What I liked: How D___t was written. How Pandora was written. The fight scenes. The elements from previous generations. The villains. The names given to the O Cs
. How one of the characters names is an anagram of "il penis". (I found it amusing) How vagracorn sounds like viagracorn. (I found it amusing)
Why I started reading it: I think it was because TV Tropes
said it was good. And it DID start out good, but it eventually jumped the shark. But what hate the most about it is the author, he's not very nice, and actually thinks the bad things are good. I honestly think he's delusional.
