>>50980245Magnemite line love isn't unanimous, a lot of people dislike magnezone, and a few even dislike magneton. It's kind of a voltorb-electrode situstion in which the first stage is widely recognised and even liked (even if a simple design, they had to be creative enough to come up with the pokeball, then imagine a mimic like voltorb, so there's still some merit) while the evolution is a lot less liked and many even point at it as an example of bad or unimaginative gen 1 designs (even if you like electrode, you've heard the complaint many times, that it's just an upside-down voltorb). Magnemite is a decent magnet monster, you only remember magneton fondly because of nostalgia, and more were open about how they thought magnezone "ruined" the line. All 3 pokemon are decent or good gameplay-wise and had a unique typing for a long time, helping their popularity. That said, magneton is probably the only of the "glue 3 first stages together" designs that makes sense due to the magnetism gimmick, but I digress.
Klink line is an ok idea but it's not only that the progression is kind of uninspired (klinklang could very well be the second stage and an even more complex gear monster could be the final form, klang might as well not exisrmt), it's also that they suck gameplay-wise, so even the people that like them struggle to find joy in using them. Overall, because gen 5's pokedex was like a sort of soft reboot of gen 1's and everybody could see these were supposed to be your magnemite line, if you add up the lack of time to build nostalgic attachment, the burn out of the franchise, the loyalty some folk have towards gen 1, the backlash gen 5 got, and people that aren't into machine or object pokemon, it makes sense that the klink line is often hated and only a niche favorite of few.
