Going Straight was very well written, very funny and did very well considering the new setting of the show.
Fletch was still as funny as he was when inside. It was nice how Godber was included in a significant way and clever how Mr. Mackay and Fletch shared the train ride home.
Only element I didn't like was how Fletcher was this lonely, undignified individual for the most part and begrunginly relies on handouts by daughter, Ingrid.
A very good effort and enjoyed the 'will he, won't he' towards the end where he was practically being blackmailed to undertake a dodgy deal on the same day Ingrid and Lenny were getting married.
I'd like to have seen more of Going Straight. For a spin-off, it worked very well for me.
