To judge the usefulness of an answer or to see if it needs to be edited it is useful to see the full answer. The excerpt normally shown in question listings is not enough for this. You can't even say if the post is correctly formatted for the excerpt, since formatting is always stripped there.
Since the whole point of the review pages is to review posts and this can't be done soundly without seeing them in full, these pages should show the full posts by default. I know there is a "show full answer" link below each post, but having to click that for each post individually doesn't help anybody.
For example the 10k tools' new posts by new users view shows the full text for all posts, which makes it much more useful.
