Reading through some of the later replies and thinking about it, my hypothesis for why some, like TheouAegis, aren't crazy for later iterations of the CV line lies in the "weight" of the attack.
When you whip something in classic CV, it's not super-fast but when it lands a hit you get a sense of connection and damaging the enemy. It's pretty satisfying to smack around zombies all day.
And I think this brings up why LoI's combat felt disappointing compared to CV64 or LoS (despite what detractors say). LoI's combat animation looks good, like I was actually whipping enemies, but the blows felt superficial and didn't seem like they affected the enemy all that much. Sure it looked flashy, but I was never satisfied after finishing off enemies, I felt like too much work was put into killing even low ranking enemies, with tougher ones seeming like a chore.
With LoS, even though the animations for the attacks don't attribute to a very "whip-like" assault, there still feels like a good weight behind each hit and dispatching lesser enemies is quick and fun. When bigger enemies come around, you work for it, and sometimes it feels cheap, but I never felt like "I wish I could just run around these guys and get to the next area". Some may say LoS isn't very CV-like, and I'll admit there are points that should of been more focused on (I'm looking at you platforming) but combat wise I feel took the series back into a direction I appreciate. Solid hits from my whip that make me feel like the man when I kill the creatures of the night.
But in CV64, despite the horribly flawed camera, the whip action felt good and solid. I never dreaded running into enemies because I could smack their faces off or chop them up when they're close. Seriously, I think all 3Dvanias should take a closer look at this game's combat if they want to get back to a more Classicvania feel. No super elaborate combos, just solid satisfying hits and looks like I'm actually using a whip to hit things instead of a flail with a really long chain (which the combat cross is, more or less).
Does anyone else feel similarly? I know the "solid hit" of the attacks is pretty subjective and hard to quantify, but I also think it's probably what changed the most in the CV universe and has caused a rift in our little community.

I just want us all to get along.
