If you want to learn Bachata this (and the rest of the series of DVDs) are great. Tony and Claudia are fantastic in this. Even though it is entry-level it is surprisingly good grounding and I find myself coming back to it sometimes.
The first part focuses on body movements which for such a sexy dance as Bachata are honestly more important than the actual steps. The rest of the DVD teaches a small number of basic moves which are even so really cool. Just by practicing all of this you could look seriously cool on the dancefloor (as you will see when Tony and Claudia dance, to music, the moves they just taught.)
Finally there is an amazing sequence showing an impromptu bachata dance in a bar. It was filmed on someone's phone so not professional quality but somehow that adds to the atmosphere and you will love it.
