I signed up to a local store's Adventurer's League about a month ago, and we're scheduled to meet once a week. I also found it interesting in that there are a number of restrictions for players to remember, and there's a lot more organization than I'm used to as far as documenting treasure and downtime. In addition I got the impression that even if I had a registered character, I may not actually be able to transfer them into other games if they're too high a level (someone else can confirm this, I'm sure).
I thought it was a neat idea to reward DMs for running AL games.
We had started with Curse of Strahd, but a few players met up with the DM earlier in the week to start Storm King's, so we're in a weird disconnected stream as we try to manage people that show up for games.
All in all, I kinda like Adventurer's League, but like anything it depends on the DM and the group you run with.
