At heart, 4E is a game, not a simulation. I guess that's why so many people have a problem with it.
No, people are having a problem with it because the rules are very poorly made. Many basic things aren't defined and many words are given definitions which stray far from their dictionary definitions. Any thorough look at the rules quickly leads you to having to try to guess the designers intent as the rules as written are unclear or non-existent. You know, RAI, and RAW, acronyms you don't see as much of on other game forums.
