Here in Australia we are now being treated to four episodes of WR a week. Perhaps it is this rapidity of going through the series (we are now well into Series 3) that reveals the major problem with this offering.
The characters don't seem to have memories; at least they can never learn from their mistakes! I suspect this may be due to the plethora of writers and directors - I haven't really checked, but there seems to be about eight of each. There seems to be no "book" outlining the major characteristics of the characters.
Consequently the characterization by the actors is all over the place, as apparently different writers and directors have different views of how some characters should behave. Some have more personalities than Tara! (As in United States of). The rapidity with which the Tom/Izzy/Lorna triangle formed and reformed in Series 2 - when seen one episode each day - was just mind boggling.
Rimmer seems to have a memory problem. When will he ever learn that Steph is a problem for him - perhaps never as every writer seems to want to do a Jack and Steph get together one last time.
There are also major gaps in the storyline which seem to defy logic. In what world is Lewis Seddon - would-be thug and general waste of space - going to suddenly (but without any explanation) going to pop up as a kitchenhand in the very canteen his family tried to destroy only two or three days (as we see the show) earlier?
