I think he is great. I love the amount of control he has over his voice, it is really incredible.
I have liked him since he was young too. I went to see Menudo in 1986 and it was the time when it was trendy to wear tank tops under button down shirts that you left open. I had gotten a new tank top and was standing at the stage when I caught his eye and he gave me a funny look. After a few minutes I looked down and realized that my tank top had slid down and revealed my bra, accidentally flashing him!

At least I had on a nice bra!
