I got the feeling that the Galaxy moved beyond Tomalak. He'd make a good war leader, but a poor cold-war leader.
It reminds me of a guy I worked with in real life. He was a smart guy, ex-RUC and Special Branch so clearly not dumb, but in a business world he struggled with an assistant manager's job of a middle sized operation. That's largely how I see Tomalak, he's fine with procedure, discipline, etc. If you hired him to work for you he'd be there on the dot every day, immaculately attired, but if I was hanging out of a window you'd have to tell him to help me up.
