Money back + 8M $ in less than 3 months is a failure?

First off I haven't watched this film but I read it bombed
and people are blaming people why it bombed.
Director Smith is blaming Willis and Willis is blaming Smith
and some other scenarios in between.

Now, I had a look at the numbers and I don't get it.
It says Cop Out premiered on February 26 with a budget of
37 million dollars.

Less than three months later on May 16 the film had
made 45 million dollars in the box office.

That's all the money back from the budget plus an additional 8
million dollars.

Of course, 8 million dollars isn't a whole lot of money in Hollywood,
but it could have been a lot worse. A failure (to me anyway) would be
if the movie only made 31 million and they ended up 8 million in the red.

They made money on this movie. Again, I haven't watched this film but who in their
right minds would have expected much more? It's not like this is Mission Impossible or Avatar or Titanic
or Lord of the Rings or Harry Potter, films that everyone in the world went to
the cinema to watch.

It's just a action comedy, get real.
And it's not like Willis & Morgan could ever achieve what for instance Gibson & Glover
did in the Lethal Weapon films.

Lethal Weapon 2 made hundreds of millions of dollars but it is a whole other film
in a whole other time. Late 80's (no internet), sequel, household mainstream big name actors.

National Security (2003) in comparison made 35 million at the box office in just about 2 months,
and later made a total of about 50 million.

Cop Out probably landed at around 50 million too. How is that bad?
It's not great perhaps, but how can people say it tanked and bombed?

I don't get it.
