I'm very pleased with your post, I'm a big fan of him and I don't always understand why he gets so many criticism.
I'm aware of the fact that his technical abilities aren't the best and his first touch still needs to improve a lot. But if you look at him at the start of his Everton carreer these points have already improved a lot.
Lukaku does what a striker needs to do and that's scoring goals. Another problem is that he depends a lot on his teammates, it's not the type of striker who can run the show on his own. But if he gets a decent supply he is lethal and will keep on scoring goals. People often forget how young he still is, I'm sure he will keep improving.
