Folk were moaning about the performances against Accies and Livingston after the break, so he can't really win. If he hadn't changed shape, he'd have been criticised too.
Hearts played a back four, with Smith taking long throws, against Dundee a few days before they played us. The system we used was wrong on the day but, again, if he doesn't try to combat what he expects from them and we lose goals to them from set pieces or crosses again, he's criticised.
Folk moan about not having a go at Celtic; you saw in the first 10 minutes of the second half yesterday what happens when you go 4-4-2 and press them. I was glad TW had a dig in his post-match interview about that.
No manager gets it right all the time but thankfully we have one that does far more often than not. Also thankfully, most fans appreciate that I think and those that don't frankly wouldn't be happy with any manager we had, it's simply their (footballing perspective) nature.
