during and after series one around 5 or 6 heroes have died or just not returned.
around 4 new ones have been introduced one of which has been killed.
i just dont see how it can be more "busy" when there are the same number of characters as before. maybe even less.
This has been a great series and for the people who complained about the first series being slow are probably now complaining about the great speed of the new series. it flows amazingly well and its quality television
