I remember a time a few months back when Cramer said BIDU was no good, a bad investment, etc. He repeated this constantly which was annoying as I held it. Then it took off and he changed his mind and tune. So, in this instance with KRY I'll take his opinion with a grain of salt.
He also used to say LU was a great stock, then in time became his "burden to carry" (or some such terminology) as it underperformed for month after month.
I think he is very smart, but no one is right all the time. I weigh what he says, do a lot of reading and make up my own mind. In KRY's case, I'm still in. Almost two years and holding now.
