Rambo and Krrish

There have been serious discussions (almost leading to nerds hitting each other)  about the titles of the Rambo films:

First film was named First Blood.

Second, Rambo: First Blood, Part II.

Third, Rambo III.

Fourth, Rambo IV or John Rambo.

The problem is with the naming of the third film, it should have been named First Blood Part III or Rambo Part II but you don't mess with Sly Stallone. 

A similar incident happened in the good ol' Bollywood when the same trick was pulled by Mr. Roshan with his Krrish franchise.

First was named: Koi Mil Gaya

Second, Krrish

And third, Krrish 3. 

Although, when asked by a reporter, how could it be Krrish 3 when it should Krrish 2 or Koi Mil Gaya 3, Mr. Hrithik Roshan said that they followed Rambo's path. 

Alas, they repeated the mistake. Truly a copy-cat.
