NobAkimoto, while you tip onto the anti-Enterprise side of the fence, I think you've got about the right attitude. Personally I think you're a little pessimistic, but then this is all about personal preferences 
You mention that there're some good episodes and some bad. Copying old plotlines is actually pretty standard for the first season of any Trek show (I still remember the fuss amongst the hardcore fans when "The Naked Now" was first aired for TNG - "Two episodes in and we get a sequel? Shocking!"), and I think basically gives the writers the chance to establish background and characters before getting into serious story-telling more suited to the era. I keep forgetting "Fortunate Son" when I list off the episodes that seem to be the good ones (probably because I'm more interested in Vulcans and Andorians than merchants) but you're right, it is one of those that promises better to come.
It is annoying when they fall back on things like holograms and Klingons, but it really isn't that big an issue!
Archer is a twit, but I think that's intentional. He's not Picard, a born diplomat, he's an engineer who built a ship and demanded to be the Captain. He's still learning what it tales to be in command on the frontier. Maybe he has the most interesting story of the lot planned?
And I agree on the Enterprise. People are paying far too much attention to the design. When you see it on the screen, it doesn't look that advanced. I'd say the comparison is more of a First World War cruiser (generally quite functional but not sleek) as compared to one from the sixties (sleek, streamlined) or the nineties (optimised for new advances they didn't know about earlier - nuclear power or stealth for example). The TOS and movie Enterprises are still my favourites.
I maintain that the show has a lot of potential. I'll keep watching until it I feel it fails to fulfill it.
