Seriously? We had regular "why rituals suck" threads on this very forum, it's the equivalent of 3E's perennial debates about monks, and 5E's about its skill system. It's heavily controversial, is the point.
While a lot of players like the general idea of having codified non-combat encounters, I've never seen anyone who wasn't a hardcore 4E fan actually
like 4E's implementation (and a lot of hardcore 4E fans dislike that part of the game,
and it was widely mocked in the LFR public campaign). Of course, this is exactly why both of 4E's successors (5E and PF2) haven't reused
anything resembling 4E's ritual system, except reusing its name for something that works completely differently.
Anyway, the forum search button is right there, so feel free to look for some old threads here at GITP
