Some reviews are written by professional critics who have extensive knowledge of cinema. These critics provide detailed analysis, highlighting both strengths and weaknesses of a movie. Their reviews can be quite reliable, offering valuable insights into a film’s artistic and technical aspects.

On the other hand, many reviews are written by ordinary viewers on platforms like Google Ratings, IMDb, and social media. These reviews are more subjective and can be influenced by personal preferences, moods, or even biases. For example, a fan of a particular actor might give a movie a high rating just because their favorite star is in it, regardless of the film’s overall quality.

Moreover, there is also the issue of fake reviews. Some studios or marketing teams may post positive reviews to boost a movie’s rating, while competitors might post negative reviews to harm it. This makes it harder to know which reviews are genuine and which are not.

Despite these challenges, reviews can still be useful if approached with a critical mind. It's important to read multiple reviews from different sources to get a balanced perspective. Look for common points mentioned by various reviewers, as these are likely to be more accurate. Ultimately, the best way to judge a movie is to watch it yourself and form your own opinion.

In the end, while movie reviews can offer guidance, they should not be taken as absolute truths. Being aware of their potential biases and limitations can help you make more informed decisions about what to watch.
