That's how I like her best, though. A less conventionally attractive looking version of the character helps cement her status as something of an outside in the wider world of superheroes, which is always invariably full of gorgeous, perfect looking people. It helps make her stand-out. That's why I was originally sort of rooting for a Kirsten Schaal type for the role (I was actually extremely keen on Kirsten Schaal for a while before having to face the fact that she's just too old now to play the character).
At the end of the day, it's always the talents of the actor in question that matters, not so much what they look like, but still...I feel that would have been a more interesting choice.
