It's very easy to pick faults in both ToD and TLC. Only Raiders is the flawless of the four films, and even then it still has a couple of narrative problems. It amuses me no end that KOTCS is singled out for being worse than any of the other sequels.
As for Sankara, I always felt sorry for the guy. Somebody with that much love of Indy with that that much merchandise in his collection and he couldn't even like KOTCS just a little bit, that's sad. It shows the danger of becoming obsessional about something. In his mind Indy finished when they rode off into the sunset.
