Amazon UK say that Battlestar Galactica Season 3 will be on sale in 4 months. Is it worth buying?
Rememer, no spoilers! I haven’t seen it yet!
I’m buying it and I’ve seen all the episodes. So if you enjoyed the first two, I’d say yes. I can say no more.
On the whole, yes.
Season three is extremely uneven. There are a couple of embarrassingly bad episodes, and some of the soap-opera stuff drags like crazy. But the overall plot really moves forward, and when it’s at its best, it’s as good as it’s ever been.
And best of all, on DVD, if you find a given episode to be subpar, you can immediately queue up the next one, rather than stew for a week. 
IMO if you have to ask, then no. The first two seasons were better.
