Although this is the first episode of a really great HBO series, I think that this first episode is really hard to follow. Not only are you being introduced to characters on the fly, which is fine, but in the next second you have no idea what their names are, and pretty soon you associate to them only by their faces.
This episode is all about the training before the war, and the introduction is really nice into this mini-series. The first few scenes really get you hooked in, and it takes off like a rocket. However, next half of the episode is painfully slow, creeping along with the men talking about how Easy Company is the best platoon.
Not a lot of story, it's just scenes of them in the training camp, but overall, it's a good start.
