Reviews at Major Spoilers need to be current and fresh.
The current review window is seven days beginning the day a single issue comic is released. If a comic arrives on Wednesday, a review of that comic needs to be complete and released on the site by the following Tuesday.
Unfortunately, the comic book and pop culture industry follows a news cycle similar to other media outlets – once the “new” has worn off, it is “old,” and the interest level of reading “old” content drops off dramatically.
There are exceptions to this rule (Retro Reviews, Random Access Memory), that do allow for reviewing older comics for nostalgic and historic perspectives, but for everything else, reviews need to be completed within the seven (7) day window.
