The fourth season of BSG has been something of a damp squib. All the pyrotechnics, intrigue and excitement promised by the unveiling of four of the final five Cylons, a Cylon civil war and the return of Starbuck didn't really materialise. 

We've had some good moments, such as the switch by Tory from tedious PR woman to psycho robot, the airlocking of Cally and the shooting of Gaeta, but the overall tone of the show has slipped. None of the relationships between the characters have felt true or even really figured at all in the show this season.

To a certain extent, we can blame both the writers strike and the crushing mythology of the show, which has been threatening to overwhelm everything. Fortunately, with the arrival of both the Galactica and the rebel Cylons at Earth, we can perhaps hope that the next season will be more interesting, less mythology dominated with only one question left to answer – who's the final Cylon and is he/she the one who's been orchestrating events?

All the same, this finale was a whole lot better than previous episodes, with tension aplenty, answers and a superbly bleak ending that will hopefully have a superbly bleak follow-up for the fifth season. 

I'll keep my fingers crossed though.
