I suppose you must have missed the parts where the purifier was over-run by enclave troops, you get captured, fight your way out of their stronghold, destroy it, and take back the purifier in a giant assault backed up by the BoS and a giant robot. With some mods, it's really quite the hardcore and deadly battle. If you know what you're doing, (read, if you've beat the game once), you can find your dad in less than 30 minutes. Just walk up to Vault 112 and save him, done. Even as a new player, it's easy enough to get clues, maybe an hour or two of quests, if you don't dawdle.
The point isn't how fun the quests are, it's whether the motivation for your character makes any sense. You actually admit to having missed the part where you stumble, forced, bleary eyed out of what was essentially the universe, without direction, and resolve, for some ill explored reason, to find a man who ran out on you with nary a farewell, leaving you to be a arrested for a crime you didn't know about, and stumble around the world asking strangers if they know where the hell this man has gone.
You then decide that you, who could be anything from a saviour and hero of the people, to some nihilistic sadist who manages to blow up an entire city within hours of finding out civilizations still exist, will help daddy turn on some arbitrarily large scale water purifying device.
You then briefly do something that makes sense, stopping a plot to kill thousands of people, a group which happens to contain you, albeit only because you happened to be in the area at the time.
Since you've already foiled this plot and destroyed the only thing planning to perpetrate it, you then spend the finale of the game fighting a war between two reclusive techno-hoarding military organisations over who gets to flip a switch. Literally. That's it. Since the Jefferson Memorial will provide water to everything, there's little benefit to being the one sitting in the control room.
That game was STOOPID.
