I read some pretty negative reviews of Star Trek: Nemesis before going into the theater, so I was not expecting much.  So, when I was not presented with much, I was not terribly disappointed.  Nemesis would be pretty good, if Star Trek II: The Wrath of Khan had never come out.  The similarities between the two are many:  the ship is lured to an out-of-the-way planet in the beginning, you have a villain who has a deep hatred for the captain built up over many years, this villain is in control of a device capable of mass destruction, there is a ship-to-ship fight that takes place in a nebula leaving both ships heavily damaged, the villain begins the countdown for the weapon to go off, and a major character is sacrificed in order to save the ship.  I can't argue with their rationale for using Wrath of Khan as a model, but I do take issue with copying it so closely with an inferior villain. 

Nemesis begins with the wedding of Riker and Troi.  We then jump to the ship where they get positronic readings from the surface of a planet near the Romulan Neutral Zone.  Apparently, positronic readings only emanate from androids, so the ship has to investigate...for some reason.  Once they arrive on the planet, they find that the android parts are from a precursor model of Data and they are attacked for no reason by people in dune buggies.  Oh, also, at some point in the beginning, someone disintegrates the Romulan Senate...or something.

So, Picard decides to meet with the new praetor for the Romulan government named Shinzon, who turns out to be a clone of Picard made by the Romulans with the expressed purpose of killing and replacing Picard at some point.  I guess they threw that idea out because they enslaved Shinzon at an early age and made him work in the dilythium mines of Remus.  Shinzon is no Khan, first of all.  He is young and bald and not very scary.  Also, and to his detriment, he is not played by Ricardo Montalban.  I'm of the opinion that most villains should be played by Ricardo Montalban.  Anyway, Picard figures out that Shinzon doesn't really want peace and a fight breaks out and somewhere along the line the movie ends.  The plot is really inconsequential because if you're familiar at all with Wrath of Khan, you already know it.

Here are some more specific scenes that bothered me.  If you are going to have an inconsequential hand-to-hand fight, then do it with people who are cool to watch fight.  They build up this race of Remans to be ferocious warriors, and they carry these cool knives.  Who do we know on the Star Trek team who is also supposed to be a ferocious warrior and carry a cook knife?  Is it a fat Riker?  No...but that is who engages in the fight, and it is decidedly unspectacular.  Also, if you are going to kill off a major character, do not replace them with an exact duplicate minutes later.  It kind of takes away from the sacrifice.  At least the original Star Trek crew waited until the end of the next movie to completely bring Spock back to life.

If you consider yourself a sci-fi person then it is your duty to see Star Trek: Nemesis, just as it was your duty to see Star Trek: Insurrection.  Just go see it, take what you can from it, and you'll be done with it.  I am making it sound worse than it is, I think.  It really isn't bad, but I don't think I'll ever need to watch it again.
