It may well get cancelled...its a tough world for us tv series... but it is watchable..
Have to remember that a lot of shows take time to warm up...eg Stargate SG1 just got better n better with time... However it is a big problem with anyone other than Wes playing Blade so my focus is more on the other characters...
As for Eureka, according to Wikipedia:
Eureka was also the #1 cable program for that Tuesday night, and was the highest-rated series launch in SCI FI's fourteen-year history.[1]
Wow... Will definately be checking out this badboy

Thanks for mentioning it dangel.
