Very few Pilots hit on all (even most) cylinders (BSG, LOST). Many Pilots that had a lot of problems (B5) go on to become fantastic shows.
It often takes a few episodes for the writers and characters to come together and find the characters, Arc pacing and World building are very difficult to balance to the audience's satisfaction these days, with audiences being so patient (I've even seen the same show where some have complained the arc is going way too fast, while others complain nothing happens every episode
).
I think Falling Skies hit some pretty good marks in these first two episodes and is off to a good start, and I hope it continues to improve.
