No franchise is going to hit 1.000. Whenever an entity like Star Trek has been around for as long as they’ve been, you’re going to have some misses. No matter how good you are, you’re going to struggle at some point. That’s life. That’s entertainment. Even the best creators stumble.
Not every Metallica album is the Black Album, not every book by J.R.R. Tolkien has the popularity of the Lord of the Rings trilogy. Even your favorite steak house or pizza place will deliver subpar products every now and then. That’s just life. Entertainment at this level is no different. Especially with nearly 60 years of content to search through.
You’re going to find films and shows that don’t live up to the lofty expectations that come with the name brand. So yes, some Star Trek shows are going to be bad. Which ones are is entirely up to you. Yet, the arguments for every show differ.
