I thought the chemistry between Dex and Fiona was, actually, surprisingly strong. Although, the idea that former military would be welcomed at all in actual crust punk or even Fiona's glam-pop-punk circles defied belief.
Who was taking care of Axel while she was overseas? Also, I really, really wish they stop having people, especially Dex, patronize him with 'buddy'. It's become the new 'My pops!' (see: How To Get Away With Murder) for me.
I find Grey just as dull as Hoffman, but painful to look at and really wish they'd conceived more complex and realistic supporting characters as anchors to the narrative. Watching those people eat dinner together sounds like a real bore.
I'm entirely unfamiliar with the comic upon which this show is supposedly based, but it's hard to imagine anyone would have had enough interest in it to option, develop and bring it to series if it's as watered down as this show is, for the most part. Hardly a rough edge in sight for a series that's premised upon a barely functional alcoholic trying to be a P.I. and which has a bar as its primary location.
With tonight's episode, I think it would have been more interesting for the long game, if Dex had sat there and done rails with Fiona and genuinely contemplated running off, leaving Axel in Grey's hands. If she, ostensibly, already has her shit together, what's the narrative arc?
