I agree. Not gonna mention any names here, but in most cases, the people behind them either don't really get the source material at all or they want to do something different but corporate mandates get in the way.When making a remake or a reboot of an existing property, the previous source material should be a rough guide, not some holy text that cannot be changed or contradicted. I would rather a creator try to put a new spin on an old property rather than trying to slavishly reproduce something from the 80s for kids today.
Sure, there are some exceptions, but when the bad ones are bad, they're painfully embarrassing.
Now I have nothing against reboots as long you got right people to handle it, but I always prefer original ideas than reboots, to be honest.
If they want to reboot something, that's fine, but you have to either do something different (while paying respect to the original source material) rarther than playing it safe and pander to people's nostalgia or just leave the property alone.
