Well, as a long standing (sitting and laying down) Star Trek (and more importantly, Sci-Fi) fan, I have to say that I like Enterprise... The first season for a series can be a little fraught with problems - the series is new, the actors have to get used to easch other and comfortable in their roles and be convincing... Season 2 was better, still a little wishy washy at times, but some good stories... Season 3 is far superior... It is more gritty and shows the darker side to life... Not all spit and polish and "we are better than them"... It was nice to see the Enterprise get beaten up... And the crew being dirty... And a nice twist with T'Pol and her "problems"...
I look forward to Season 4 (as it has been confirmed that it is to continue)... I hope they have another season long story arc...
I also like Smallville... I dunno why, I've read Superman comics, seen the films and series'... I was expecting to hate it, but find I really enjoy it...
The Next Generation was the most successful Star Trek series, because people were ready to see what could be done in the 1990's, and the number of Star Trek conventions at the time was unbelievable... I should know, I helped organise a number of them... Then when DS9 started, there was less interest, due to Babylon 5 starting at the same time... With Voyager, again there was a resurgence of interest... But Enterprise seems to be seeing a tailing off of interest in not only Star Trek, but Sci-Fi series in general... What with the cancellation of Odessey 5, Earth: Final Conflict, Firefly, Farscape, Jake 2.0, Babylon 5: Crusade, etc... BTW Anybody ever heard of a series called Starhunter??? Only lasted 2 seasons... No, I ain't heard of it either...
Maybe it is time to put Sci-Fi away in a box for a while, until the world is ready to take that step into the future again...
