All Halo games are quite decent as they offer a certain experience. There is the issue that some titles have a different storytelling mechanism, and tackle onto new characters, and ideas that haven't been introduced in previous releases. That sometimes causes people to be disturbed as an element they are not used to is introduced and it doesn't meet a certain degree of expectations that they may have.Halo: Reach suffers of some issues, not just in the story, but also its mechanics that were a different direction from what the majority of the playerbase that was willing to move from Halo 2 had adapted to at the time.Always take negative opinions about video games on the internet with a grain of salt. Most people who do have a truly negative opinion will provide a realistic argument besides what has been rehashed by others who may be either random people's posts on forums, websites, blogs or videos, or some professional writer for a publication.
