Season One has a lot of what was wrong with Season One of Lost, lots of running around to disguise very little plot movement, you could edit all that really matters between the first episode and the last down into an episode in itself without missing much on consequence, season two it finally kicks into gear although loses it's way between Admiral Cain getting shot and Lee being made the captain of the Pegasus. Season Three starts off very strongly then is just good for the rest of the season.
Season Four seems to have gone off the rails somewhat. There seems to be any number of crazy ideas being thrown at the screen with little apparent care and attention. Part of the cause of this was presumably the strike, but it's something of a mess. The writers never seemed to give proper care and attention to the fact that Cylon society consists of a near infinite number of seven models but now it's all over the place, so that the Cylon Occupation of New Caprica was run by a particular selection of skinjobs, who just happened to take Baltar off-world with them, who just happened to have a De'anna on board who went crazy over who the final five were, who happened to be the ones who took Hera, who happened to include the Six who has visions of Baltar who then decide to revolt, who just happens to include the Leoben obsessed with mentally torturing Starbuck to bring her closer to God. I really dislike that pretty much everyone except Six now is referred to by whatever name we first met them in the show, One is not called Cavil! Three is not Deanna! Why was Brunette Six called Natalie? Who knows!
Then of course, after their ship is attacked, the Cylon civil war only happens off-screen but just constantly gets referred to, while instead we get to thrill to the adventures of Lee Adama and Rollo Lampkin the crazy kingmaker. Oh, and Lee's President. It's alright to write an episode criticising the social order of the Fleet but not if you're going to decide that things can't go on without an Adama heading the military or government.
And Saul Tigh, one minute Bill Adama's fighting him for sleeping with Six, the next minute he's making him acting Admiral of the Fleet. There's a lack of consistency here.
Still, it was nice to see Colonel Kira though.
