Flash done well is great. It can be overpowering or annoying however. I remember the first Tomb Rader and X-Men sites had a repeating soundtrack. I could not stand to stay on the frontpage for more than a minute, which I guess was the intent. As long as it does its thing and doesn't keep going over and over demanding attention it all right. Pages load fast if done right. You can get better feedback from imagemaps when you are in active zones.You can generate motion or animation without big MOV files. Cool stuff!
