I just bought this Riverdance, and also have the older version shot in Radio City Music Hall. I like this one better. It is longer, for starters; about two hours. It shows close-ups of the dancers feet, which I liked. I was wishing the girls were wearing something besides black tights and dark skirts against a dark background, so I could see their legs better. But, the dancing was very good. The orchestra, with an assortment of instruments, was quite appealing. The violinist dancing around while she was playing was nice, too.
In Michael Flatley's DVDs the costumes are much more colorful. I would have preferred more of that. Bright colors are nice. I never could understand the storyline, if there is one. It includes the Irish dancing, which is why I wanted to buy the DVD. But it includes black tap dancers, which you can see all the time on television. The story includes traveling to other countries, other shores. Why, I do not know. It seemed forced. I would have preferred more Irish dancing. If they needed variety, they could have included some Scottish Highland Flings, or sword dancers, instead.
I only buy DVDs that I intend to watch more than once. This certainly is one of them. I do plan to go back and back to it, watching it over and over.
