You mention "good" and "Brexit" in the same sentence - would you care to expand?
The parliament and court of a foreign power no longer has primacy over ours end of story, and it doesn’t get any simpler than that.
Because we have left and it doesn’t affect us now, there is positive/benefit/something good that can be counted for every single policy area which is covered by qualified majority voting in the EU, and that expanded very significantly with the ratification of the Lisbon Treaty, i.e. no vetos whereby if you don’t like it tough sh&t even if your whole country is against the eu legislation for that area.

As such we are no longer have the overarching rule of an immovable Blairite (the most successful Liebour party leader is now universally pilloried as a lying warmonger re wmd’s, which is bit more serious than some cake and a party lol) style centrist government regardless of who people actually voted for in this country.
Of course the leftist quisling sh&te will always essentially chant better foreign rule than tory rule, but that’s because they’ve largely given up on getting into power (hence chasing the PR dream) and are happy to override what people in the UK vote for because ‘they know best’, their attempts to overturn the ref showed their true colours on that score.
Personally I would even vote left rather than for foreign rule, so the gift that really keeps on giving though is that if the leftist sh&te hadn’t want to have their cake and eat it and Corbyn (how many ex tory leaders have essentially been kicked out of the party?) had stuck to his Bennite Eurosceptic roots, instead of doing a 180 and ditching his ‘principles’ at the first whiff of power, we could have had a Corbyn government now implementing it’s socialist dystopia.
Because a pro brexit liebour party would have very probably have beaten a tory party which then would have become more remainer dominated.
So instead it’s the likes of me that gets to have our cake and eat it, tories in power and no longer having to work within parameters set by Brussels. Fk yeah !
