Scarlett Johansson Black Widow Movie... No thanks

Looking for some feedback on this one but having seen Iron Man 2 and knowing that MARVEL is planning a Black Widow spin off movie it begs the question does anyone want to see Scarlett Johansson reprise the role from Iron Man 2? I for one do not.

In simple terms Scarlett's role reminds me of Jessica Biel's from Blade Trinity. In Blade Trinity Jessica Biel's character was wooden, over the top and completely off kilter and as much as Scarlett wasn't as bad as Biel was in Blade Trinity I have a hard time believing that she could carry the role.

Her character had very little to say or do in the Iron Man 2 movie but throughout I kept thinking to myself how miscast the role seemed to be.

Clearly having an attractive actress is key but for me it needs to be a grittier character which I am not sure that Scarlett can pull off. Do you think she did a good job as Black Widow? If not who would you have liked to see play the role?
