I liked it - the final season started really slow, but ramped up to the end, which was more intense than I was expecting. I do like the final events and was happy to see that the character who actually ended it all was the one character that drew the most criticism over the course of the series.
I agree that a two hour finale would have helped, but I think it was cool too - this is our plan, it's our only shot, and it has to work. I also like that the strigoi didn't just die, they were just left without a communication network, making them easy to finish off. Of the past seasons, I loved Eph and Dutch's attempt to jam their communications, so it was nice to see that they didn't move away from that that info.
