With this version of 'The Odd Couple' being more of an ensemble show rather than solely resting on the heads of the actors playing Oscar and Felix, the writers by this stage of the first series have started having two story lines per episode, one featuring Oscar, and one featuring Felix, with the supporting cast being split accordingly.
The Oscar story line isn't funny. It's a premise that has been done to death in sitcoms and there's nothing really new being added to it.
The Felix story is far better, and features the ever developing Felix/Emily love story, that has been well played by Lindsay Sloane. The addition/more regular use of Murph is also a bonus to the show too.
It's an episode of two stories really, one good, one bad.
