Jodie's era is definitely my least favorite of the revival show (not watched most of classic yet, plan to over the summer now the newer series has gotten me back into the show properly). However i don't think the casting was a problem. Jodie is a good actor in other things and a few scenes here and there feel well done. The problem is there isn't much of a story in the episodes she's in and not too many of the standalone stories hit well. There's no 'Blink' or 'The Satan's Pit' essentially no unique standalone story which really feels written well enough to stick with you. And the ongoing story in her era felt aimless and so many retcons which at this point don't really feel right. I do however think she's a good actress and fits as the doctor, just it'd be interesting to see how she'd have felt under Moffat or RTD writing her.
