I’ve been in similar situation where my manager was more focused on micromanagement without regard to the big picture and he wasn’t supporting us, or guiding us efficiently so I had a one to one chat with him and he was totally understanding. He actually wasn’t aware that he was micromanaging, and honestly changed his management style after that but not every manager can be very understanding when you speak with them about such issues so make sure your words are politically correct if you decide to talk to them because there is a fine line between criticising and constructive feedback.
On another note, I do agree with Kiron, if this is not affecting you and it’s just your perception that he is not adding value or being productive then let him deal with this with his superior. This is not something you should get involved with.
