Books and films
Rated on a scale of 0-5 stars, with half-star increments.

5/5: Absolutely amazing and the peak of the medium . Not just excellent writing/ plotting, imagery/ camerawork and voice/ character arcs/ acting...
But also including a strong emotional aspect, fantastic message about our world and/ or exploring, examining and bringing to light a meaningful topic.

2.5/5: Average. By no means a bad effort, but either some really great stuff with some pretty "meh" content, or an entertaining but otherwise impact-less experience.
TV Shows
Really difficult to judge a TV show objectively in the vast expanse of commercial television - so each episode is rated as good, ok or bad (usually with an emoji scale relevant to that series).
Music
Impossible to rate, as it becomes even more subjective here.
Takeaway
Importantly! Whilst my ratings attempt to be unbiased, they are undoubtedly influenced by my own subjective and personal experience/s.
Therefore, the most important thing is to read the articles for yourself and note where and when I recommend a book/ film/ TV show/ album - as it will be dependent on your personal tastes! Each and every reader will be different.
