Another pointless remake?

If you are of my generation, then you probably saw the 1948 film "Brighton Rock" when it came out at the cinema (I had to sneak in because I was under-age).  A classic, and a masterly performance from the whole cast - particularly Richard Attenborough.  How can you hope to improve on perfection?  Why even bother?  The only possible - if rather feeble - reason would be to remake the ending which deviated from the book and many people (but not me) thought was a cop-out, but apparently they haven't even done that, so why????
