For 10$, yes, deffinatly YES. Other M is a rly good game overall with some flaws. I prefer the Prime series but I enjoyed the game and for only 10$ its a GREAT value.
As for an introduction to the franchise, I think if you have no plan on playing Super Metroid, Other M is a good introduction cause it indroduces what happened during Super Metroid with Mother Brain and the Baby. It also has (unlike prime) the traditional sidescrolling gameplay elements that the franchise is known for.
