If there was ever a good rebranding that stays true to history it's this one. A dead lion swarming with insects isn't the most appetizing thing. A lion with a bee reminds of the story in a tasteful way. They could have kept the biblical quote.
For me it completely loses what made the original special, specifically that it wasn't appetizing. The juxtaposition was delightful and I would often buy jars of it for a laugh. Now it"s just another sweet syrup among many.
The packaging (tin versus squeezy bottle) isn't changing — they already sell both.
Only the labels are changing, and they're keeping the tin (specifically) unchanged: https://www.bbc.co.uk/news/business-68347249
