First, that's the wrong use of "theirs" you mean "there's" as in
the contraction for "there is." It's not really important, but little
things like that might make some people take you less seriously.
Second, while it's fair to say that :
1) Cap made more money at the box office,
and I have to agree with the previous poster that in today's terms
$59 million isn't all that much,
2) It was better received by critics.
Despite those facts I don't think you can label WB a failure just yet - given that the Hobbit films seem to be doing okay ( having made about $1.9 billion so far) and the Harry Potter films probably helped them too (as the last one made about $1.3 billion).
If Box office is really important then Transformers
ark of the Moon, "crushed" Star Wars, ( compare 36% RT score for transformers and $1.123 billion to 93% for Star Wars and $ 775 million) and also Dark Knight Rises "crushed " Dark Knight. hmmmm...... maybe box office isn't that important after all. Face it folks, people will pay to watch garbage (which is why Tim Burton's Alice in Wonderland film made over a billion !) as well as good stuff.
If you liked Cap 2 better because you prefer the character, that's a fair call. Personally, I thought it was okay. Which is saying a lot for me, as I can't stand Captain America as a character. After coming out of the Dark Knight, I just had to see that movie again (which I did, four times, and I felt the same about Man of steel), after seeing Cap 2, I was entertained, but if I don't see it again I probably won't miss it.
But then again, that's just me.
