I only tried the tutorial in remix and still don't get the use cases, probably because it's a new way of development compared to the traditional MVC?

I thought it's still missing a lot of stuff compared to rails / other battery included frameworks? The closest one comparable right now is redwoodJS

Probably because it's unopinionated? for instance how would you setup middleware, events, logging, etc?

Battery included frameworks like django, laravel, rails, all have extensive docs and way to setup everything. Also jumping between those frameworks already gave you familiarity due to the mvc structure. Now i'm probably just confused, from mvc, to spa and api, now to SSR with data fetching and processing happening all in 1 file?

Maybe the docs need to be better. or i'm just not good with new stuff..
