They did a great job. Unfortunately (since I haven't watched the series) I can only say that if the pilots are as immature, undisciplined, and idiotic in the series as they are played in the game, it's a wonder the Cylons haven't destroyed all life by now.
I also evidently really, really, really suck at Freespace2-derived games. Not sure why--I loved the old X-Wing/Tie space sims, but in Freespace2 I can't hit the broad side of a barn.
None of this detracts from a very well-done free game, though; worth a look.
