I'm not gonna say why you should like this show, as you don't really have to like a show just because i do.. (SPOILERS!!)
But, i have to explain some things that you must've missed, this isn't your average show, you have to use a different mind-set to watch such a show, sorry, but i love how subtle the show is for its huge scale and character importance doesn't depend on what said characters have done, but rather about how important they are in "The Game of Thrones". (What politics is called in Westoros)
Robb Stark's death meant that the whole rebellion has ended and that what is only left of his army/followers is some stranded soldiers stealing, looting and plotting revenge on the plotters, offing a character like Arya Stark, for example, is useless to the plot, offing Arya would mean that her whole independent story comes to an end, but when you off a PLAYER (What politicians are called) you start a chain of events that are generally chaotic due to them depending on the family/allies of the player having to choose their course of action.
Let's say Robb wasn't betrayed, the war would have changed in pace and became much slower as the North needed to recover what is theirs, Winterfell and aid the Night's Watch if possible and with them holding Moat Cailin, it would've taken their enemies from the South of westoros a while to recover and attack, which meant that Stannis Baratheon would've had to deal with every other southern lord, and that the north would've had to deal with the iron islands and the wildlings.
But with Robb's crucial death, Stannis may have a better chance of escaping the south and the "iron men" could take some castles and cities that belonged to the north whilst the north is scattered, dying, plotting and forming alliances.
That's an example of how one death can change everything, plot-wise. (Whilst others died, Robb was the most important character who did die)
This isn't a show like Arrow where they'd off a character because of the emotional effect offing said character would cause and move on after a while, it's a show where one character's death is extremely important to the course of the whole story.
Again, you don't have to like it, but that's where you were pretty much incorrect and i like how the show doesn't like to treat you like a moron whom lacks sufficient braincells to understand what is happening... (As you might know by now, i love politics)
