I agree. The ENT showrunners should have picked a lesser known actor. At first, every time Bakula was on screen, he reminded me of Sam Beckett; even later on, every so often when he was on the screen, Sam Beckett came to mind.but I really wish the production team had chosen a lesser known actor for their acting ability & suitability for the role as opposed to a celebrity for the sake of his status.
Not only that, but I wasn't impressed by his portrayal of Archer. He came across as a relative lightweight, especially when compared to the other ST captains.
The following is totally irrelevant from the topic. I remember there was a ridiculous reference to Bakula during one scene of an episode of Buffy the Vampire Slayer. One character mentioned Scott Bakula's name. Then another character replied in a fanboy crush sort of way "Captain Archer". That was so bizarre and ridiculous that I remembered it.
