I have a very different opinion on this.
In the Bilateral series that take place the ODIs are of little consequence. All Bilateral series are about the tests, and much less about the ODI series that invaribly preceedes or follows a bilateral test series. All Bilateral tours are about the tests. The ODIs hardly matter, and infact I don't remember many bilateral ODI series involving Ind but I do remember nearly all test series and their results. That just shows that bilateral ODI series are not even comparable to bilateral test series. In any bilateral series the tests are the real deal. ODIs are a sideshow for the most part. T20s on any bilateral make even less sense to me and are the closest thing there is to absolutely meaningless cricket. A group of school children playing cricket makes more sense to me than Int'l T20 cricket. T20 should not even be played at an Int'l level let alone have an ICC event. In any bilateral series its all about the tests.
However there is another side to ODIs and that is when it is not part of bilateral series - Tournaments. The two biggest tournaments cricket has to offer WC and CT are both ODI format, and while it is okay to not care for bilateral ODIs, not caring for the major tournaments makes absolutely no sense to me.
Sure there is the never ending test championship, which no one quite knows when it starts or ends and is just perpetually going on, where the scoring system doesn't exactly make any sense to anyone either, and there is never any finality to it. It just forever goes on, forever rolling and at any given point in this never ending system, some team is at top and is that team is hailed as the #1 test side, and presented a mace, and that is a great feeling when that side happens to be your national side, but its hardly a real tournament by any stretch.
So saying I don't care for ODI cricket eqauls saying I don't care for my side ever winning a major cricket tournament, which is something I don't understand. I want India to win every test series, but at hte same time I want Ind to do well in the major tournaments.
Also you can't be sad over not winning a world cup. You can at best hope for a good run, to say the semis or Finals. That is par of the top sides. What happens then on is something to be cherished not expected. No team goes into the world cup saying I will definitely win, each side, depending on what its stature is, tries to outdo the expectations. So while SA or SL, will be hoping to at least make the final, INd hoping to atleast make the semis, Afghanistan will try to reach the second round, that will be a great achievement for it. If you fail to achieve this min requirement then one could be disappointed. No team goes into any WC in any sport thinking they will definitely win or will be disappointed. No world cup in any sport is just about the winner. Its just about outdoing the min expectations for any team in any WC. For one side getting to the SF is par while for another getting to the QF is setting the bar too high.
