Anyone here just read 1 or 2 of the ultimate books and not the others?

I am new to the Ultimate Universe and I just ain't feelin Ultimate X-men at all. I kind of enjoy the Storm/Collosus plot but the Jean Grey, Quicksilver, Witch, ect plot thing that is going on just leaves me confused as hell and frankly, bored.

But I really like the Ultimates and Spider-Man ain't half bad.

Will the Universe just get confusing without reading all the books? It isn't like the 616 where there are 100000 books so losing one isn't a big deal. Not reading Ult Xmen would be losing 1/3 of the universe... My pull list is just so gigantic that I need to start cutting back some.

Thanks
