The first Season is the best, the 2nd good, the 3rd has slipped on a downward spiral and the 4th well it has dropped to the lowest in my estimation. I feel that they became too involved with the personal lives of the main characters and repeating too much that some characters began to irritate me. The series is /was a magnificent attempt starts wonderfully and gripping your attention so much that you cannot wait untill the next disc. This first 2 seasons of the entire series had me hooked -then it lost its momentum becoming far too involved in each character until I wanted it to finish and see the end. Which was unfortunately in my opinion a let down after a marathon visual experience. I would have like to see more Space action than centralising around the sexual needs of the characters. I purchased the entire series and I enjoyed the time ,I do not regret the purchase and would recommend it hence the 4 stars - I feel the end could have -should have been better. If you haven't seen this BSG then Purchase the entire series the first 2 seasons will grip you and for that alone it is worth the watching.
