It took me a long while to warm up to ENT, but now that I have, I agree with most of the points mentioned here.
Is it just my own tastes, or does ENT go out of its way to provide fanservice for the female audience, more so than the other series? That's probably my favorite thing about this series - seeing that someone in charge bothered to pander to female scifi fans. Having Troi and Seven in sexy outfits is fine, but ENT also gave us numerous gratuitous shirtless scenes, which I totally appreciate.
The entire male cast stayed in shape for the whole run, though maybe that's not entirely fair to mention since it was only 4 seasons long. ENT never made us watch that sad, slow decline of hotness into pudginess which afflicted Riker and all of the VOY male cast. The DS9 guys maintained their "middle of the road" bods (except Miles O'Brien, who never should have had a shirtless episode), and I suppose the TOS guys also did well, but I'd say ENT surpasses TOS in terms of the quantity of hot guys.
I might be alone in this, but the Xindi arc did nothing for me. It was OK, but not all that gripping.
