Yeah maybe a little, in real life I don't think any of them would have ended up as CEO, but out of the lot he was probably the most competent; its clear that Kendall wasn't up to it, Roman didn't want it and Shiv ****** it (although its not like Mattson was going to give her it anyway).
I almost feel like we could easily have had another season with Tom in charge, and seeing how that goes while we see what the kids do next.
I do love Tom though (I'm a huge Matthew Macfadyen fan generally since his Spooks days), he's been one of the best characters throughout along with Greg. I think he was genuine with Greg - during this season he's been put back "in his place"
