I watched all the eps that I had downloaded - 101-106 - and the show does get better. Slowly, true, but some improvement really is there. On the other hand, it's still missing... something. I can't put my finger on it but there's just something a little off.
It feels, at least to me, like the cast has no chemistry. It's like the actors go through the motions, repeating their lines but the... spark, I would call it, is not there. It feels a bit like SGA season 1 - Sheppard and McKay were what was holding the show together for me but the team didn't really click until Ronon joined them - and with Sanctuary's team it's similar. Nice, likable people but they just don't stick together as a unit for me.
Also, the horrible CG background in most of the scenes is quite annoying. It feels like looking at those pictures that you need to stare long and hard at to see what's in them - the shape then leaps forward while everything else blurs. That's what most of the scenes feel like to me.
Should the show appear on DVDs, I would probably go for it if it's cheap enough and if there are extras but I don't see myself downloading and watching the series regularly.
