What phrase best completes the sentence: I always enjoy this film, no matter how often I see it?

The phrase that best completes the sentence is "I never tire of this." This construction effectively conveys a sense of enduring enjoyment and repeated appreciation for the film, emphasizing that regardless of how many times it is viewed, the viewer continues to find pleasure in watching it. This aligns with the sentiment of consistent enjoyment expressed in the first part of the sentence.

The other phrases do not fit as well in the context. A phrase indicating forgetfulness or lack of enjoyment would contradict the sentiment of always enjoying the film. Similarly, expressing weariness would imply a negative feeling, which does not match the idea of consistent enjoyment.
