When theories get 'large' then the location of our observations within that theory becomes just as important as the rules governing them. We need to take both into account when using Occam's razor.

For example, explaining observations using multiple-worlds QM is very simple in terms of the rules used, but has a very complex "location" within that theory (ie. pin-pointing which Universe those observations are being made in).

There's a nice overview of this idea in http://www.mdpi.com/1999-4893/3/4/329
