If I were to rate this it's really broken down like this.

Black Adam and Isis Arc - 2/5 - Boring and kind of just there. There's a few glimpses of interesting character development but the rest is just meh.

The final two part story 1/5 - Boring, bad dialog, nothing connects.

The farewell issue - 4/5 - It's a birthday for stargirl and it's really well done. Has heart, humor, and well done dialog that we've come to enjoy in this series.

I'ma have to go with a 2 out of 5 for this one because only one good thing worth reading. However, just for that issue alone read it, skip the rest.
