Even though my opinion is not recorded there, I'd be the first to admit I felt the previous set were a weird replacement for the dragons (and the whole temporary rebrand that lead up to them was even weirder). I still do think they're weird, but somehow felt very very Welsh and suited the output of the station. Certainly, I could not imagine them in use on any other station.
With these idents it's just the opposite - they don't feel particularly Welsh, and while I can't say they don't suit the channels output they certainly don't feel as though they were customised to suit it.
The logo I can live with; and I even quite like the interaction around the DOG
The previous set were great and were a nice departure from the lazy cliches that are so easy to fall back on in Wales (dragons, male voice choirs, sheep, etc) with a nice metaphor running through most of them.
They really are playing it safe with this new lot - they speak of a channel that doesn't like to take risks, which might be nearer the truth than the older set.
