I guess it depends on what you consider good or bad. Personally, for me, ICS is good. I have not had any major issues and my only comlaints are visual ones. Namely, I don't know why they got rid of the color notifications for all black and white ones, or why they made a data roaming notification pop up every single time the phone goes to roaming with no way to make it not show up. Oh, and the lack of FB integration, thus leaving my contacts with no pictures associated with them (unless of course they have google+). Others have more complaints, so again, it's subjective. YMMV. Even with the few things I could pick to complain about, I am loving having a newer version of Android.
