Thanks! This is exactly what I wanted to know. Is it pretty much a continuous plot-line throughout? (Movie-->Season1-->Season2)
Yes, though some episodes are more stand alone than others.
In the first season there are "stand alone" episodes that are 100% self-contained and "complex" episodes that are a part of the main plot.
2nd GIG gets a little more complicated, where most episodes at least have SOME referencing to the main plot in some ways, though some are more stand alone than others.
This episode, for example, has Motoko in Taiwan following the trail of a particular person of interest that the entire main plot revolves around. Once she's there, though, she gets into, well, all these antics that you're watching, which have little to do with the main story.
