The Hadith is a very wide and complicated area of study, but one thing I know for sure is that the majority of Shias agree and accept the Hadith, as said by Propher Muhammed, they might disagree, however, on who narrates it (on behalf of Prophet Muhammed after his death). I think I need to mention here that they only take those said by Ali Ibn Abi Taleb and his family as the most reliablt source of all. One area of difference between the Sunnis and the Shias is that of marriage, and the laws of marriage, but not even marriage in general, certain aspects of it, and certain cases of it.
Other disagreements are drawn from the fact that, while Sunnis have Four different Imams (as in four different people with reliable interpretations of the Hadith and Qura'an) for the Shias these four are not as reliable, as the main principle of the Shia is that Ali Ibn Abi Taleb is the right, deserved Imam of Islam (they also believe in 12 different Imams whom are all from Ali Ibn Abi Taleb's family). Even with all this, Islam has five principles that we all as Muslims agree on, maybe some cults would 'perform' them differently (like certain cults in Shia, they differ in how they 'perform' their prayer, but not in the content of the prayer itself).
In general, I know it might sound that we disgaree on a whole lot of things, but if you read in Islam jursiprudence, you'll know that eventually, these are minor details, that weren't even looked upon or noticed before the war in Iraq in particular.




As a side note, I work with a few muslims. In fact my boss's boss is mulsim, and I've known him a long time. I'm not sure if he's Shia or Sunni. He's from India.
So it's not really off topic. We provided an example.
