I still play and enjoy 4E, and was heavily involved with the 4E community at the time. I don't recall a ton of people in the community being ACTIVELY excited by Essentials. It didn't generate the vitriol of the anti-4E crowd either though. A lot of the community felt it was unnecessary, and that it signaled a shift in WOTC support away from the things they liked in 4E (I guess they were right) and some thought it was just another way of doing a new edition and getting people to re-buy core books.
Not sure of the reaction outside the 4E-fan community, but I'm not aware of literally anyone who didn't like 4E pre-Essentials, but then decided that with Essentials they did like it. If there were some, they were a really small minority.
"pointless" is probably the simplest description most people would agree to: 4E fans basically shrugged or sighed unhappily, and 4E haters didn't change their minds. Maybe WOTC made some money off it, but it didn't change the game for them, so pretty pointless for them also
