She was great as Faith but I don't think she has the chops to pull off multiple characters for a full season. It's a tough role to do and I think should be the most entertaining part of each episode. Sadly, it's just Eliza in glasses or caring a briefcase etc.
Sorry Eliza, but the show really is on your shoulders (as a Producer as well) so any blame would have to be pointed at you.
My vote would be Firefly, felt like I was watching a movie every week.
Normally I'm a fanboy that complains, but with Wolverine if I get the claws and the action done right, then I'll be a happy camper.

Or, just go back to old X-Men books and pick a good story to copy. It's not like 'Heroes' has done anything original yet.
