I like the steampunk gimmick, in that it does feel real for Becks.
It's like when AJ started as the geek girl, the fans loved it because it was AJ. Her whole angle where she was basically hooking up with every guy with a briefcase didn't work because that wasn't her. Then when she was the passionate, half bitchy one because she hated the "Divas," the fans loved it again.
Becks I think can be an evolution of the angle, but it's not an angle.
Let Becky be Becky. Let her be into steampunk, into half goth stuff, into cosplay (I wonder if they took that from her for Alexa, actually), into being nerdy and quirky. Let her cut promos full of corny puns and silly jokes but then bring the intensity when it has to be.
That's the Becks that stirs my loins.
