Before anyone posts that "no one liked" a certain movie because they themself didn't like it, let's look at data....
RT Fresh: Is just a thumbs up or down based on critics' ratings. Think of it as a "see it / don't see it" recommendation.
Avg critic: Taking the average score of the critics' ratings from Rotten Tomatoes and Metacritic.
IMDB & RT user Avg: The websites of Rotten Tomatoes and IMDB allow users to input their own ratings. The RT score is more susceptible to 'bombing' because it has a lot less audience scores. The IMDB ratings are usually from hundreds of thousands of users and harder to bomb.
CinemaScore: This is from a company that randomly polls audience members at the theaters on a movie's opening weekend. It is normally a little bit higher than the average audience score because people who go on opening night are generally more predisposed to like a movie they went out of their way to see on opening weekend, especially for genre films. Thus, when a genre film doesn't score well, it's a very bad sign. Sometimes a movie surprises an opening weekend audience by not being what they expected, and it gets low scores, but, over time, still does rate will with a general audience (e.g., Nightmare Before Christmas).
Budget: doesn't include 'hidden' costs like advertising and production company overhead, which is, as a rule of thumb, and extra 50% of the budget.
Gross: The Box Office take. Which is, as a rule of thumb, split between the production company and the theater.
1/2 Gross - 1.5xBudget: The rule of thumb profit of loss... in the theatrical window. Movies move on from the theaters to make more money through PPV, DVD, cable, streaming, merch, etc...
ROI: Rate of investment: A movie cheaply made, but with a $100M profit has a much higher ROI than a movie with a huge budget that 'only' made $100M.
The movies listed as "D+ and theaters" were released directly to D+ in the U.S. and in a few international markets in which theaters were open and that market didn't have D+.
