An opinion can't be ludicrous, and if other opinions bother you so much to the point that you feel justified in being insulting, condescending and arrogant, the perhaps you need to step away from the message boards and take some time for yourself for self reflection and self improvement.
Yes, an opinion can be ludicrous. I'll demonstrate: My opinion is that you are wrong, and you need to respect that and reflect upon how poor your character must be for disagreeing with me. And worse, insulting me over it! Perhaps you should take some time for reflection and improvement. Or at least get over the holier-than-thou white knight complex you have going on.
Sorry for the snarkiness, can't help myself sometimes. If you think every opinion is equally valid regarding art, do you ever read reviews? Do you put any stock in the contents? What if you read a positive review of Superman 64 (one of the worst games of all time), and based upon that positive review you wasted 50 dollars? I suspect you would be pissed off, because the review was
wrong. How does that gel with your opinion that it's all subjective, in this hypothetical? The opinion of the reviewer is, after all, his subjective view and to him the game might be the best time he's had since injecting glow stick goo into his veins*, but objectively the game is awful.
The story of Fallout 3 is just as obviously awful, and if you don't think so.. fine, don't think so. I'm not going to go into another back and forth debate on the difference between objective and subjective. Note that I'm not saying that Fallout 3 as a game is awful, here, as people have misunderstood. I am stating that the story, characters, and dialogue are massively flawed. The game excels in almost every aspect other than the story and characters, however, so the game can still be great despite the problems.
*Don't actually do that, it will kill you dead.
Edit: Upon rereading the original post, I think I just got trolled pretty hard. A pretty well crafted piece of trolling, though, so I have to give some props for effort.
