I am a big Hercules fan. I still remember watching this show back when it was still on the air, but now I have to watch them on dvd.
I loved this movie, but I didn't think Iolaus played a very big part in it and to tell you the truth, I thought he acted kind of stupid. I guess that's why he didn't last very long.
I knew of course that Hercules was going to have to go back in time some how, because Iolaus has to be around for the tv show. Sure enough, everything turns out in the end. It was a great episode/movie.
