I like it because it's Star Trek. It fills my need for ST, even though it may be flawed in many ways and certainly not the best production in the entire ST franchise.
If your trekie enough, and good enough at deconstructing a story, you can probably find a recycled plot structure behind every Enterprise episode to date. They seem to be taking the bare-bones plot from former series and just adding enough differences to make it look original to the casual observer.
And the ending to last weeks "vanishing Hoshi" episode was such a cheap cop-out. I was actually getting into it and was excited to see how little Hoshi would save the ship. But then they go, "oh, it was all just a dream!"
There is a literary device known as "Deus Ex Machina" which comes from the Latin for "god from a machine" and essentially means the intervention of a nonhuman force to resolve a seemingly unresolvable conflict. This is pretty much what they did with that it-was-all-just-a-dream-ending.
They could have shown some major character development for mousy little Hoshi after mustering up the courage and the cleverness to save the ship. I think the writers did what they did because they want to start making more use of the transporter in upcoming episodes and they felt a transporter disaster such as this one would have shut that down. I still think they could have gone a long way with character development by having the crew somehow overcome the disaster and still convince Starfleet that the transporters were still worth using as human transportation devices.
The biggest flaw with Star Trek: Enterprise is simply poor writing.
