After that, however, it began thrashing around, although Jaime Murray's 'real' H.G. Wells character went a long way towards saving the third season. (And lets forget about the Eureka crossover/computer game episode which was painfully embarrassing to watch.) Unfortunately, they've also done a lot to make the characters less and less likable as the series continues. Probably in the mistaken hopes it will inject some additional 'depth' into the plots. Or plot as the case may be. Because there really is only one plot: "Snag it. Bag it. Tag it."
In a way I expected this. W13 is basically a one trick pony. It was only a matter of time before the blush started to wear off.
H.G. Wells really did breathe some new life into the show. She reminds me of Claudia Black a lot.
Some shows have a lot of depth, others, not so much.
Some great examples of shows with zero depth are NCSI, CSI, Criminal Minds, and pretty much most cop shows. I almost feel embarrassed for Gary Sinese in CSI:NY - he's a much better actor than the show - it's beneath him - and the character is beneath him. I just can't watch any of them anymore.
Both Eureka and Warehouse 13 have that rigid style that boxes it in. They've done a few good things to break out of the mold, but haven't quite got the knack of it.
For shows with better depth, I think Supernatural really does a fantastic job. Some things I'm not all that keen on, like how Dean just always has a bad attitude - he's a much more likeable character when he's not being moody. But, overall, extremely well done.
I think Felicia Day, Jaime Murray, and Claudia Black all bring that certain je n'est cais pas to the screen that few others do. It's a lively, bright, happy character that you just can't get enough of.
Many other characters are moody, depressing, angry, etc. That gets really annoying after a while, and one of the reason's I really loathe Gary Sinese's character on CSI.
