In terms of overall quality of the show itself - no question, but this collection? Lets see:
The picture quality for all the "remastered" talk, seems no better than other releases although it looks good for the 1st series.
The extras are fine, but it's strange why they stopped at The Cavalier Years and didn't include everything, all the comedy specials, the pilot, etc.
What's most disappointing, however, is the commentaries. Surely everyone involves has watched a DVD with the commentary on - so have a clue what one needs if making one. Yet they're rather woeful here. What all the commentaries are, are just listening to them watch the episodes - which means large parts where they're not talking, then bits where they're just laughing, then bits where they just describe what a costume felt like, or "XX is funny in this bit". Where's the talk about the series, about memories, about behind the scenes stuff, talk about the process, tidbits, anecdotes?? There's also no commentary for any episode of the 1st series, which was a let down as well.
So yes, a good collection but honestly - it should have been great.
