[quote name='bigdaddy']That's because the writers have poor management of time and wasted 90+ minutes in the last two episodes.[/QUOTE]
If what you're saying is why couldn't they have planned more in advance and crammed some of this into season 3 or 4.0, sure I can see that. It's just been bang-bang-bang: earth is wasted, corpse starbuck on earth, ellen resurrects, cylon backstory becomes clearer, mutiny, council gunned down, gaeta executed, roslin returns with boomer, cylon fetus dies, hera kidnapped, so on. Big themes and big reveals are dropping like flies.
On the other hand, I think it's disingenuous of viewers to expect a writer--or worse yet group of writers---to sit down and say, "Here's 5 years of episodes. Now let's shoot them." They had an overarching idea and they've oscillated around that as they saw fit. Ideas have come and gone, and they're just running with the best stuff they can come up with.
I guess my main complaint with the writers would also be directed at the producers: if you had all these great ideas that unfortunately came a little late in the run of the series, did you at least consider extending the run a little? Just to give every story its due? I'm sure SciFi would've loved to have had another half season of episodes to space out over another 4 years.
