As for Lee, look up what his fans did to Longstreet and anybody who questioned Lee's generalship. If people criticize Lee now, maybe it's only fair, given how his partisans attacked anybody who stood in their way.
Some of the criticism relates to Lee's generalship. For all his brilliance in some campaigns, Lee wasn't able to form a winning strategy to win the war. Perhaps that was because he wasn't in over-all control of Confederate forces, but if he was, maybe he wouldn't have had the time to win those battles. Of course the Confederacy didn't have the resources the North had, but given that, shouldn't Lee and his fellow Southerners have taken another course of action?
Other critics take on the myth that's grown up around Lee as some kind of saint. Lee was so revered and with so little questioning or critical investigation, that it was inevitable that people would become skeptical about his reputation. If Lee's high reputation was deserved, it won't be entirely destroyed by current criticism.

McArthur was but a side show. He had a whole division wiped out in Korea because he stubbornly would not believe there.

Until Summer 41', the Army was using the Philippines for dumping screw-ups and other undesirables.
It was MacArthur who finally ended that practice but it took time to fully implement that he didn't have.
Japan would have had a hard time taking the Philippines in Spring 42' if his build up had continued. It would have been impossible by summer.
