Yeah for some reason all modern Trek (TNG/DS9/VOY/ENT) have a bit of a lackluster Season One. Some argued that it was "finding it's way" but series have been cancelled for less, and most TOS Season One eps don't get as bad a rep!
Season Twos seemed to be a little hit-and miss - yes TNG's Shades of Grey,
I see you hiding there behind that "But I was just a bottle show" placard!
But almost universally, they all hit their stride at the Season Three mark, and Enterprise is no exception.
Stick with it, and you'll be rewarded.
