I haven't seen the new one yet, but I can definitely agree with you for the most part. I actually really liked Gabriel at the very beginning of the series with her angelic side. I would have preferred if they fleshed out her slob personality and built up to it rather than just have a quick change.
Honestly, thank goodness for Vigne. I mostly prefer her over anyone else besides Satania. Those two really make the show for me!
And the introduction of Tapris last week kind of made the series take a downhill plunge in my eyes. Not a super big fan of her personally.
Anyway, that's been on my mind about this show lately. Glad to see I'm not the only one who feels kind of "over" it as well.
