Not Happy with Vampire Diaries This Season Grrr

I'm going to take a second to rant about Vampire Diaries. It seems like the bad guys are always winning on the Vampire Diaries and nobody good ever catches a break or when they DO catch a break there is some awful repercussion for doing so. They've killed off a record number of characters and brought back a record amount of characters. You never know if someone is really dead. Most of them come back. I feel like the writers have run out of ideas and there have been some serious plot holes this season. For one thing,  I don't understand how no one is aware Katherine is still alive! Bonnie saw her when she died for two seconds.. SO Catherine would have to pass through her to get to the other side and she didn't. Also they seemed to be revisiting the Damon gone bad plot AGAIN and it's getting kind of old. Same with Katherine. I don't like this whole thing where they take good characters and turn them bad. First it was Damon (OK he was bad from the beginning), but then we saw Damon change and become better (or so we thought). Then it was Stefan. He was bad for a season and then he finally came back to being good. Then it was Elena. They turned her bad for a season. I think they should keep the bad guys bad and the good guys good. It's just getting redundant. I'm pretty happy with the Originals. I hope they keep that show on the same level it is right now because in my opinion it's ten times better.
