Bought season 4.5 last Tuesday and finished it about 20 minutes ago. Wow, I love this show. I agree with what you guys were saying about Lost and BSG. They really are the two best shows post 2000(and for me both are in my top 10 of all time) because although they have sci-fi trappings, they rely on the strength of the characters, writers, and actors more than most shows do. They don't win as many thing because of their sci-fi elements but I think we'd all agree here that they SHOULD.
Oh, and I also agree about Alias and Smallville. Alias started off great and it seemed to have a plan but I'd say after the third season ended, it became all about pleasing the network and making it more accessible and it just becamse very one note and directionless. I'll never forgive them for how bland they made Arvin Sloane who pre season 3 was slowly becoming one of tv's greatest villains.
Smallville's problem is it just doesn't know when to die. I felt seasons 1 and 2 were fun but 3 and 4(by far the worst season for me) were just treading water. Then we got the phenomenonl seasons 5 and 6 which really should've ended things...then it didn't. Season 7 came and I liked it well enough but again, it should've ended(especially with Lex leaving. How do you let Lex find the fortress...and then keep going????!). 8 was...well, better than the worst Smallville seasons but it reeks of beating a dead horse. The worst part I've heard about 9 is that they still think they can go for 10! That's nuts.
Back to BSG, now that i've finished the show again, that list of my fave episodes I mentioned a few pages back, will finally be ready. Expect that soon and I urge you all to chime in with yours too. In reflection of season 4.5, I think it has a weak middle but not as weak as many claim. What has affectionatly become known as "The Gaeta mutiny/rebellion" to many is easily the strongest part of the season but while the middle is well...middling, it still has stuff going on. Mainly resolving a bunch of dangling plotlines like Boomer and Tyrol's former relationship, the oddly formed triangle of Tigh/Ellen/Six and the...baby, etc. It's not as great as earlier stuff but at this point in the series, we care so much for most of the characters, it feels better than it probably is. And the finale still rocks, I dont' care what anybody says. Other than the kind of flimsy way they handle Starbuck's deal(which after THAT much hoopla and buildup IS poorly handled no matter how you slice it), I think it's perfect. The deaths are touching, the action is awesome and(I wish I had a gif or something of it) but as we all know Galen choking Tory=awesome.
For those who are on the fence about buying the rest of the series, I urge you to do so. Many are divided on the final season with it's focus on the final five but nobody denies the awesomness of the first arc in season 3: the new Caprica occupation. Those episodes are better than most major motion pictures, they're so good.
Finally, my Chief Tyrol action figure is now on it's way to me. Yay!
