Well I watched Awwal Number when I was in high school I guess. 11-12 years back. At that time, cricket being a craze to me, I hadn't "hated" it that much. I consider it a bad film but I'll not name it in the top 3 worst films of Aamir. There's still Love Love Love which beats Awwal Number for me.
In the question you mentioned "name maximum 3 films", I did the same. Actually naming only 3 is indeed minimum as each of the Khans have more than 3 worst films in their career.
