About the cliffhanger...
I am judging it partly based on what I know comes later, but even when I didn't know that I didn't like how it undercut the ending of the Xindi arc. So much stuff happened in season 3, a lot of it (
Azati Prime -
Zero Hour) taking place in little over a week. Archer tortured a man, pirated from innocent aliens and had the weight of the world on his shoulders for a year. T'Pol is a recovering drug addict who is returning to a situation of divided loyalties. Trip only just learned how to deal with his sister's death, and a number of people in his department died at the hands of the Xindi. A number of people under Reed died too, and he had the stress of all the boarding parties and space battles he was responsible for, and he has to deal with the death of his rival, Major Hayes. Phlox has been overworked, especially since the attack at Azati Prime, and he helped to create and murder a sentient being. Hoshi was tortured and almost responsible for the destruction of her homeworld. Travis... Travis... well, the ceiling almost fell on top of him, so he might now have night terrors about... ceilings falling on top of him.
My point is that these people have been through a lot this year, except Travis, and now that the arc is over I'm interested in seeing how they will adapt back into regular society, I want them to come to grips with what happened to them. I want what
Family was to
Best of Both Worlds. If the show wanted to give these characters one final kick in the gonads before they get their rest, as in BSG's
Revelations, then they should have had a cliffhanger that had something to do with the Xindi or the sphere-builders, it shouldn't have been something completely unrelated. Instead we get a cliffhanger that doesn't have anything to do with the Xindi arc, and we have to sit through an unrelated two-parter before we finally get to the episode I want to see.
Lack of effort is the key - give paragraphs of explanations and a series of graphs and it'll look like you put real thought into it.
I did put real thought into those graphs, I learned how to use MS Excel 2007... which was easy because everything is in a simple to understand ribbon interface. But I had to pick the colours!
