Having used micronaut for a few years now, I hate it.

Maybe it's innate to trying to use a a fully fledged server-style framework in a serverless context, but I don't think it's suitable. In fact I think the whole idea ("Hey, let's bludgeon spring-like metaphors into an entirely new setting") was a poor one.

Java itself I've enjoyed more and more over time as the language has evolved into something much more expressive, and without all the enterprise crap. My hope is that one day frameworks like Micronaut will end up discarded too.
