I think that they spent far too long setting each joke up, for example: the ironing joke at the begining (I won't describe it any further than that for those who haven't seen it yet) could have been half as long and would have been funnier as a result (it was obvious that a joke was coming since they kept circling the same small phenomenon in greater and greater detail for no apparant reason).
It was alright but it didn't have the same 'feel' or 'atmosphere' that the old Red Dwarf's had (the cheesy effects and sets/props, due to the low budget, gave it a lot of charm and gave it a distinct look and feel, now that some of the stuff looks shiney and good it's lost that unique vibe it once had).
