Comics are even more subjective than movies. Reviewers tend to be cynical spoiled man children with anal retentive sensibilities. Never trust reviews just read for yourself.
Like I said if you want to read Wonder Woman stick with the books I mentioned. Don't know about Harley because I have never liked that character but Batgirl and Black Canary are pretty good. Same with Starfire (from the same creative team as Harley Quinn's book).
Darkseid War is very self contained. All you need to read is Justice League and it's well worth catching up with. The one shots are only supplementary not obligatory.
