I went to rehab, and part of my inpatient rehab requirement was to attend AA every night. It was impossible NOT to go, because it was right there in the recovery center. After I left rehab, I went to AA a few times on my own but I didn't stick with it.
Even though I didn't stick with it, I am pondering a return at some point. I'm coming up on 7.5 years clean - AA was indeed very helpful for me in those first few weeks as I was learning about what it means to live sober. I don't have anything bad to say about it.
