He was quite a fleshed out character, more so than Harry or Tom. Even if you think he was a jerk or inconsistently written he was not bland.
Gotta give him that.
The most interesting thing about Harry was how he was going to get rejected or suffer this week.
Tom Paris? Lotta potential... but let's see... he's a hotshot pilot, a skilled field medic, he can pick up any woman he wants, he can lead commando missions, he designs and builds ships in his spare time, he invented a completely new propulsion system(some side effects), he's a history expert, and basically he can do anything else the plot requires. Tom Paris is a Mary Sue.
