alright, this show never had the best actors or CGI's. It was just a low-budget sci-fi show. Although Jonathan LaPaglia isn't the best actor in the world, I liked his character (Frank Parker) because he represented the show's motto: It didn't take itself too serious. (like most other Sci-Fi series.) I even remember when Frank made a joke saying something like "this isn't a low budget sci-fi show". I was never a big Sci-Fi fan but this one I liked.
Besides the great basic idea, I also liked the relationships between the characters. For example Parker and Olga, teasing each other all the time. Or Ramsey and Parker who despised each other.
To sum up: I think you won't find any other sci-fi show like this, including great plots about time traveling but also being fun.
