"Simply the best"
Pimsleur is, bar none, the finest language instruction program on the market. You will need to kern the very com ex writing system elsewhere, but for grammar and vocabulary, this is the top of the line. Every language student should try this program. It works, and this from someone who routinely failed a language as close to English as French. I cannot praise this program highly enough.

It's not all bad. When Chopra is playing in his accustomed sandbox, he's got his a game on. If you're into that, you might like it. Comic fans, don't bother.
