Still haven't tried actually dancing it (not well enough *sniff*), but have watched the intro, all the routines, and some of the explanation bits.
My first impression is that I'll enjoy having a go at it and I'm glad I bought it!
Obviously having only watched it my thoughts are based on impressions of how hard things are, music etc. But better than nothing I hope!
Explanation wise I think it suffers from the same thing as Latinacise, it's just hard for pros to put things in a way a clueless non dancer can understand, and I found with Lilia's vid too the easiest thing was actaully just to do the routine, watch the bits i couldn't immediately follow, dance the bits I could catch, and gradually work up to being able to follow the whole thing.
Some great music choices and some deliberate (and IMO fun

) allusions to former couples' routines - Jill's jive, Denise's QS, Mark's salsa among them.
Think I prefer the warm up and cool down to Lilia's, partly because of better music choices, partly just I think better routines.
The routines themselves look fun, in places more complex just in terms of lots of different stuff going on than Lilia's, but in some places I think possibly less physically demanding. So probably good for me whose brain works slightly better than my body!! LOL!
There's no slow routine like the rumba in Lilia's workout, but I the cool down has plenty of rumba inspired movements and could fill that spot. It would have been nice to have a more chilled routine in there though.
The jive in particular looks less scary than Lilia's

and maybe will help me work up to one day trying to get a grip on Lilia's routine! It has some deliberate "have a rest" type spots worked in so there are places to get one's breath back.
Can't really say, having not actually USED it, if I think it is better than or not as good as Latinacise, but I think I will enjoy it and will probably still use Lilia's vid, so for me it's a good addition to my selection of "work out vids that aren't deadly boring"
Hope this is vaguely helpful, will try and post something more conclusive when I have actually USED it
