Bakula is completely lacking in subtlety. You never hear anything unspoken in his voice or see it in his face.
Many people (including myself) think that Bakula's best Trek performance was as the mirror Archer, playing a character
who was completely surface level and "lacking in subtlety." Bakula was perfect in that episode.
... maybe Connor should have played Archer.
Better still, have the character of Trip be the Captain of the Enterprise from day one. Instead of Connor playing the part of Archer.
