Old school dnd modules

I'm asking for opinions here. I'm looking at trying to get into or run one of the old school dnd modules such as elemental evil, but the more I research these modules, the more it looks like they are not fun at all. It seems like gotcha dnd with the modules actively encouraging the DM to screw over the player in dickish ways that if happened in a real life dnd game, would lead to exlax getting mixed in with the DM bribe.

My question is, are there good ones that are fun to BOTH run and play? I wanted to give some of the classics a chance, because they're, you know, classic, but my gut is telling me not to touch them with a ten foot pole. (see what I did there?) Anyways, if there are good ones out there, let me know.

I've run a few different old-school modules (Temple of Elemental Evil and Keep on the Borderlands) and they haven't seemed like an issue to me.

White Plume Mountain and In Search of the Unknown seem also relatively okay. The only real "dickish" module that I'm aware of is Tombs of Horrors... Edit: No scratch that, Dungeonland and it's sequel (the Land Through the Looking Glass IIC?) are also dickish... As for good modules, the first Ravenloft module is also quite good. Ravenloft II: House on Gryphon Hill starts promising, but then the adventure sort of stop making sense when you realized that some people somehow managed to live in a manor infested with monsters without a) getting killed, and b) finding out all those monsters lived in the manor with them...

I have been running the module In Search of the Unknown on GP since February and the players are still enjoying it. There's very few "gotcha's" that I wanted to remove or modify.

Isle of Dread has few gotchas. I highly recommend it. You will drink your DM bribe with confidence that it has not been chemically tampered with.

The Lost City is good. I modded/ran it in a Pathfinder campaign a few years back.

Kay. This is honestly reassuring. The first ones that came up when I did my research were the tomb of horrors and and dungeon lands, which were the ones that were being cited as dickish.

Are you able to adjust the modules so that you can have it both ways? Modify things to challenge the players, but keep it fun or at least not make it seem like you're trying to screw them over.

Of course. But that kind of defeats the purpose of a module right? Its supposed to be less work

If the one golden rule of an RPG is "it's your RPG, use what you want and ignore or change what you don't like", then it's not much of a stretch to think that the same applies to a module. If you can change the rules to suit your style of play, surely you can do the same to the modules. Honestly, I don't think I've ever played any module as-is...

I think the exploration modules were good. Keep on the Borderlands, Lost City, Isle of Dread

I know that Tomb of Horrors is specifically designed to fuck players over. It was never really meant to be part of an ongoing campaign anyway and was mostly used at D&D tournaments, I believe.
