I've had one a few weeks ago and normally it would have been the first of many but I definitely thought the quality had gone down hill. I won't be buying anymore as for me there are lots of chocolate bars that taste better.
I can't notice a massive difference in the chocolate taste itself but as a whole I think the flavour has reduced and sweetness increased What ok most disappointed though has little to do with taste - it was the thickness of the chocolate at the top. Now that I miss.
That and the original blue on the packaging instead of purple. <shows age>
I didn't notice much difference either, except maybe the chocolate wasn't as thick? You've reminded me to take a trip to Lidl to get their own brand fondant eggs raved about on here a few days back - I'm banning Cadbury's on principle (hate all that jelly bean in chocolate shite!).
For me it's not so much the taste of the chocolate that's changed on creme eggs but the fact you can bite through the top now instead of having a huge chunk of chocolate, and the sides collapse in as the chocolate is too thin. As the chocolate is so things, there seems to be more filling which makes it too sweet.
Dairymilk chocolate is awful now and has a horrid waxy consistency so I avoid all Cadburys except crunchies and caramel taz freddos which taste mostly the same as the chocolate is so thin.
Kraft have ruined my favourite affordable chocolate so now I have to save up for lindt or have galaxy.
