About Episode Ratings
The grades I give out range from "0=worst" to "10=best".
While this system works quite well for me, it has been subject to some confusion as I can tell from occasional negative visitor feedback. In relation to my Enterprise reviews, some people pose the question how I could possibly call myself a Star Trek fan, if the average is below 5 out of 10 points, and if I go down as low as 1 or even 0 points in some cases. And regarding my takes on the Abramsverse, there are even readers who question my sanity for rating "Star Trek: The Motion Picture", for instance, higher than "Star Trek (2009)", although the latter is more successful and so much more exciting than the first.
To clarify this issue, my ratings are not comparable to other people's "five stars", "ten points", "A to F" or other common scales. One decisive difference is that many other reviewers, especially those working for print magazines or for sci-fi, movie or TV websites, don't focus on Star Trek like I do. They use the same scale for Star Trek, for other science fiction and for completely different genres. This is not the case with my grades that are relative to the rest of Star Trek and nothing else. I wouldn't want to compare apples with oranges and, moreover, I just don't care so much for other TV shows that I would bother to review them or even compare them to Star Trek. While I certainly watch TV besides Star Trek, I think I don't allow myself to be influenced too much by it.
In brief, you could say that in my personal view a Star Trek episode with 0 points still ranks above most other stuff on TV. But to be more precise, I wouldn't even know how to compare them because it's not only the mere entertainment value that matters to me. Something that is important in my view is how an episode relates to what we already know from Star Trek, including but not restricted to originality and continuity. I have a long-term memory for everything related to Star Trek and it influences how I look at anything new. In this regard, I can explain the ratings as follows:
10 points: among the best Star Trek episodes ever, simply awesome
5 points: average Star Trek episode, quite a fun to watch but with some flaws
0 points: among the worst episodes ever, almost a waste of time but at least it's Star Trek
I go as low as one or zero points, because a rating system makes no sense if there is an accumulation in the upper half and the lowest ratings remain unused. I chose to include the zero so I can easily relate the figures to percentages, and because the average would be exactly at 5 points, and not between 5 and 6. If I calculate the average rating of all Trek episodes from all five series so far, it is slightly above 5, so the system works out also statistically.
It is true that my grades for the first three seasons of Enterprise are below all-time Trek average. But I reject the notion that I intentionally lowered the grades for Enterprise, just because I don't like the series on the whole. What could I prove with that? I don't have a problem with not liking the series so much. I think everyone has a favorite, and shouldn't make such a big deal of it if someone else has a different opinion. After all, everyone is entitled to write their own episode reviews. But looking more closely, Enterprise doesn't even rank below the first two seasons of TNG or DS9, which both had a rather disappointing start not only for me, but for most fans. In this light, I wonder about the fuss made about my alleged unfairness. Even though I initially disliked many aspects of it, at latest the fourth and final season proved that Enterprise could mature just like TNG and DS9 too.
Regarding the Abramsverse movies, I have numerous problems with the basic premise, with the plot logic, with the outcome, with the characterizations, with the many amendments to the technology and the set design, with general continuity, with miscarried homages and with visual effects. Enough reasons to impair my fun of watching and hence my ratings. As already mentioned, I have a personal way to view and rate Star Trek episodes and movie. I certainly leave out criteria like (appeal to) "popularity" or (commercial) "success" that others may take into consideration. And once again, it is no crime to have issues with a movie even if the majority seems to love it.
