Of course they are. I've never denied that Cadbury's range in the UK is now boring when once it was at least interesting.
Go back 30, 40, 50 years. Cadbury made bars with fruit fondant filling (pineapple cream!, strawberry - lots of them), they made rum and raisin fudge bars, Amazin Raisin, a huge range of different bars in the 1970s - now you are left with endless variations of things with biscuit, toffee, wafer and various 'bits' in.
