Good point on Malcolm spraying mucus everywhere. I think Enterprise's best quality was its ability to do character studies (I'm ahead of my reviews and watching Season 2's "Minefield" right now). Unfortunately their action stories sometimes suffered for it. I had always looked at Star Trek as an action-adventure format. I liked character shows, but preferred those built around a conflict that was really a thought study for viewers. "Sleeping Dogs" almost succeeds for me, but there's no real brain teaser in it.
The final scene-- yeah, in my review I mentioned Malcolm fans might get a treat. Unfortunately, we T'Pol and Hoshi fans never got a full frontal of them without shirts.
I think Doug Drexler's old blog had renders of that Klingon ship. I'll have to see if I have them.
