I actually love that the focus is on Kat this season and not on Elena, its refreshing to see and much more entertaining.
However, on the whole, I feel that Silas and Amara part could have been executed much better without making it feel rushed or dragged. Tessa was really a weird character which could have been used better,along with this Professor. Damon's past should have been explored more. I mean it was painful to watch but there could have been a different edge to him.
And whatever they did with Bonnie was just . Like it doesn't make sense...whenever they want...they make supernaturals pass through her and then she will go on, scene after scene without anyone passing through her.
God damn...do you know the bloody population in this world...how does this even scientifically make sense!?
