I would not consider Eureka as one of my favorite shows,but I do watch it in between baseball seasons.
It has great writing and pretty decent acting, considering the whole show is based on silly premise.
Just as a personal note. I would liked to have seen more of Beverly Barlow, but they didn't seem to have room for an evildoer in the main cast.
It seems that the main failing of the show was that it didn't star a bunch of snotnosed teenagers.
I guess it shows my age, but I am surprised that teens have nothing else to do but watch TV.
Which explains why they look like they are trying out for the sumo wrestling team.
