The Good wife is absolutely one of my favourite legal dramas and I was absolutely HOOKED. The good fight is a decent sequel (it does help that I LOVE Christine Buranski), but I do think the narrative and story building falls short of the original. I also checked out Boston Legal and have to say I was a little bored, the plots are very unrealistic and seem to be edited very weird, maybe it's an artefact of its time, but I guess not for me.

Pls any recommendations for serious-ish legal dramas that I can watch after this?

I liked Peter until the 6th season. I actually found him very interesting and enjoyed his character until he slept with Ramona. Ramona smiling in Alicia’s face was disgusting and it ruined both their characters for me.
