I'd say anyone that didn't find it fun was doing something wrong
I spent an entire year hating and ranting about it, then suddenly i followed a few tips and i was having tons of fun!
How I'd recommend starting it;
1. Get your explosives skill to 30, either by leveling up or during the tutorial.
2. Talk to Lucas Simms in Megaton about disarming the Nuke.
3. Get a free house for disarming the bomb!
4. Hoarde or sell what you don't need at your house.
5. Explore the wastelands aimlessly! Make it a mission to get as many locations marked on your map.
Along the way you'll level up, find awesome weapons and eventually move onto quests. The main quest isn't entirely recommended but it's not so bad, you get Power Armour like half way through.
Another tip if you're struggling for health early on, put a lot of points into your medicine skill! It makes Stimpaks more effective which is very useful early on.
