I’d argue it matters quite a bit. It shows producers, and by extension a studio, that can’t manage production effectively, and that almost always extends to the rest of the movie. “Bad” CG is rarely the only issue with those movies, it’s just what you remember most since movies in general require the suspension of disbelief and that pulls you right out of it.
The downvotes are probably because they’re just stating something obvious. No shit, bad looking CGI looks bad, that doesn’t mean the actual CGI itself is necessarily bad. Small things like wrong lighting can make otherwise great CGI look terrible. The reasons DO matter, even if the average person may not really care and just has the takeaway of “bad CGI”.
