to be honest, none of them bug me
in my humble opinion... every character is perfectly written and they make for an amazing mix. there are no weak links to me.
that sound sort of like a cop out, but its true, and its a big reason i love the show so much. everyone compliments each other and everyone has so many foibles.
the only thing that bothers me, i suppose, is that lois doesn't "get hers" enough. i love her character but she can be so unreasonably cruel for no reason, and the boys can fold too easily sometimes.
i have yet to see the final episode, but i read about it, and it appears that she forces malcolm to go to harvard and become a janitor instead of taking a 6 figure job, and that they always WANTED for him to be miserable from the very beginning. its no wonder he's a pessimist! they want him to be miserable and fail at life.
what we DON'T get to see is malcolm going insane later on in life and turning into the unibomber. thats the onlyreal en d for malcolm, and its lois's fault. thats why i love the episoe where dewey terrorizes her for the entire episode and she thinks she is going insane, after she failed to get his baking soda. they shuold have gotten their revenge on her more then they did. thats my only real gripe.
family guy did a spoof where hal snaps and offs her- and the boys walk off happy, because as hal puts it, "we're free! we're finally free!" and thats what i wanted to see more of.
