If you run the actual math, it turns out that Essentials was more expensive than buying the PHB/DMG/MM. It was significantly more expensive if you actually bought the Starter Set and everything else WotC told you to buy (instead of just the books you actually would need to get a complete set of rules).
Not really true, though. It had a higher overall potential price, but a potentially lower start price.
Previous: DM gets PHB/DMG/MM. Everyone else gets PHB. Non-discount price for a 5 person group: $240.
Essentials: DM gets RC/DMK/MV. Everyone else gets their preferred Heroes book. Non-discount price for a 5 person group: $190. Or $210 if they pick up the Red Box beforehand.
Combined with a very confusing product line-up (with inconsistently overlapping content), conflicting information from WotC about which books you actually needed to buy, and a Starter Set that suffered from the same problems that every pay-to-preview boxed set has suffered from for the past 20 years the result wasn't pretty.
I do think they could have done the release better and made it clearer who needed what items. And while I don't think the Starter Set suffers nearly as much as the Alexandrian thinks (similar to his price assumptions), I do agree that it could have been so much more than it is.
I mean, I agree, absolutely, that they could have done a better job with how they handled Essentials. But some of these criticisms seem more... complaints for the sake of complaints, rather than honest reflections of the situation. It had its issues, but it also was successful for many folks, and did present a cheaper/simpler entry into the game than we had before.
