I'm surprised ArthurDent didn't mention this one 
Would have felt like self promotion.

I tend to prefer the BBC original release, though the newer version is very good & they left the door open for sequels as they never made it to Milliways, The Restaurant at The End of The Universe, nor did they answer 'The' question. It was fun to see the original Marvin, and 'Arthur' in the new one.
