Many, many bad ones.
The ideas that I thought were good, but flawed: Anna Maria, the stint at Horizon, and Parker industries.
The ideas I thought were bad (and I know I'm going to catch flack for this): Queen Pin, Superior Spider-Man, the Spiderverse killing spree, man-child Peter, and Spokingbird.

And of course there's Renew Your Vows, which was both a rare example of Slott writing something well AND becoming a great ongoing.
Felicia appeared on a variant for that, but for some reason has not been included in the series, which is so odd...even Spider-Girl made use of her.
I've tried to read Renew Your Vows, but while I want the Peter/MJ marriage, they don't feel like Peter and MJ. They feel like generic Dad and Mom who happen to have superpowers, and Annie is the primary focus we follow. I think Spider-Girl did a better job of keeping personality in tact while constructing a family dynamic.
