It was inferior to the Kajitsu/Rakuen series when it came to darker and more tragic stories covering psychology and deeper meanings but it also had its own merits with a lot of unique characters and action going on. One thing I missed was the ecchi moments the prequels had and not enough Kazuki was definitely a downside for me.
I recommend this if you're fine with experiencing a new storyline with a different cast. But if you're watching this expecting a continuation of the Eden of Grisaia with the same story, this may not be what you want.
