Nowhere near. As a Long term viewer and an Avid EastEnders supporter I have no concerns with the show at present. I do have a couple of niggles but I am enjoying the show right now. The era's such as 1989,2006.2013 were terrible and i'd happily regard 2013 as the worst ever year for EastEnders with 2006 second.
1989 to 1993 saw EastEnders flagging ratings wise and there was talk of it being axed because it was falling behind where it was up until 86.
2006 saw EastEnders fall to it's lowest ever rating.
2015 actually is seeing episodes up Year on Year and it's had the biggest ratings since 2012.
The Niggles I have is some of the block storytelling and the lack of gritty plots but on the whole I am very much enjoying EastEnders.
