Lots of Fallout fans don't like it because it screwed with the lore (The Brotherhood as white knight heroes, The Enclave...exists, Harold, the GECK) and lost the humor that was always a part of the series.
Me? I hated Fallout 3 for different reasons, because it was my first Fallout game. Mostly, I'd say it just lacked a soul. The world just felt like random locations that have little to do with each other, and it was all visually bland or grimdark. It was an oppressively bleak game. The story was also very dumb and offered little meaningful choice until the very end (where you just pick the Stupid Evil option or the Good option). I don't think it was a bad game, but I just hated it.
I was apprehensive about trying New Vegas when it came out, but some things convinced me to play it. And I loved it. For one: I loved the faction system. It added a sense of continuity and consequence to the world. And I loved the overall story, especially how many of the side quests tied into it in some way. It had humor and interesting characters. It varied the landscape without sacrificing the post-apocalyptic or post-civilization wilderness feel. And it had things that were just there to help you immerse yourself in the world (hardcore mode, certain perks and traits, gear with a story behind it). It redeemed the Fallout series for me and made me want to try the first two games (and Tactics). That's why you hear a lot of older Fallout fans praise New Vegas and condemn Fallout 3. The latter is just a post-apocalyptic game without a soul. The former is a bona-fide Fallout game with a soul.
