This is the start of a new and interesting Star Trek series. It has a "down to earth"-kind of feel with darker and less "plaggy" scenography.
The characters need some more time to develop but they have potential. One thing that is fairly disappointing (with all Star Trek series really) is that they portray such a gloomy picture of the equality between men and women in the future when they paint a very positive picture about everything else. (Earth has stopped war, famine etc)
The female characters here are two, subcommander T'Pol who is vulcan and communications officer Hoshi who is human. Hoshi is quite wimpy and T'Pol is made to be a "vulcan babe".
Some of the crew attitudes feel a bit too American (as opposed to the more international feel of the TNG-crew) but creates interesting dynamics.
A very good pilot though for a very good series.
