As casual anime - it is indeed watchable and enjoyable.
As Mecha anime, well, 2/5.
As Evangelion spiritual follower -> it strongly 'smells' like made by someone, who thought she got the concept of the original. It is like "oh, I have seen a bus, I guess I can build my own now, I don't need to graduate from engineering uni, nope, not at all..". In such case 1/5.
I still gave it 3/5, as
