Movieclips instead of scenes?

1

i read somewhere that scenes flat out suck. as a alternative people are suggesting movieclips or loading swfs. i dont understand the movieclips idea. how can u use movieclips instead of scenes? obviously its possible to put all info that could be on a scene into a movieclip(because so many people are doing it) but how can this be done? can some one please shine some light on this issue for me? thanks alott!
