Replying to Your opinions on Flash websites?

I know, I know, flash blows dick and is dying out. I'm working on a site right now in flash (first time I've ever used it) and you can do some cool animations for sites that I haven't figured out how to do in HTML/CSS, use different texts besides a select few that you use in HTML land, etc. Do you think it is worth continuing or should I just stick to the good ol (somewhat boring) HTML.

Also, is there such a program to animate using HTML5 that would be equivalent to something like flash pro?
