if we consider the term hypothetically, based on the phrase itself, "almost quantum theory" might imply a concept that shares some similarities with quantum theory but deviates in certain aspects or has additional features. Without more context or information, it is difficult to provide a definitive answer.
If "almost quantum theory" has emerged as a new concept since I'm not interested in that topic as much as i used to and my answer might be a bit outdated, it would be necessary to refer to more recent scientific literature or research to understand its specifics and why it might be regarded as stranger than regular quantum theory. It's important to stay updated with the latest scientific developments to access the most accurate and comprehensive information.
