Complaints that are really really silly looking back on it?

Back when pokemon gen V came out the vanillite and garbodor line where LOATHED and genwunners would always use then as prime examples of why new pokemon suck and are lazy which not only are vanilitte and garbodor some of the most tame pokemon designs looking back on it but the argument was silly back then since pokemon like voltorb and muk existed since gen I.

What are other examples of "did we really used to get up in arms about this?"
