What bands and artists are consistently bad live?

I hate to say this, but I've been to three Avril Lavigne concerts in 2007, 2011 and 2024 but it always seems like she's going through the motions and doesn't have any stage presence.Her singing is also mediocre or sometimes even bad.

She's the only artist who has been bad every time I've seen her.I am a huge fan so I gave her a few chances to see if she improves or not, but she never did.She was playing with her hair all the time, especially in 2011.
