Recently watched all of Firefly (which I've seen regularly recommended here) and the sequel/prequel fillum too... okay but hardly the Saviour of Sci-Fi it's made out to be by fanfolk. Looked like very generic TV sci-fi with precious little of either involved as per usual to me. Cookie cutter TV fodder. Can see why it was cancelled given the glut of near-identical shows about at the time. Would this one have ended up better than the rest? Maybe but showed no particular signs of it as far as it went.
Other TV series I watched recently was The Pacific (as in the "sequel" to Band of Brothers by the same people). Found it oddly uninteresting. Didn't feel drawn in at any stage and got no real sense of reality from it as such. Yes it was all grimy and dark and shouty and grim and all those other Spielberg/Hanks WWII stuff cliches they're so big on but felt... hollow to me. There are campaigns that lasted months in reality which pass by in minutes with no real sense of truth beyond the fact a main character gets killed now and then. They spent a fortune on this thing but felt like it was churned off a mill with no real care and attention. All that seemed to go on very specific details (of which there are plenty going by all the bonus material bumph - battles correct down to individual bullets and that near enough) but nothing in terms of connecting those details with wider reality. I suspect the main issue was trying to condense 3-4 years of (hi)story, plot, character and action down to ten episodes. Just ended up with no real sense of any of that stuff leaving little beyond grubby blokes shooting at each other in the rain. Disappointing.
