Hi Goods
I had a major problem with this chapter also. In fact, I am sure I posted about it in Jan/Feb time as I was struggling also. In my humble opinion, this chapter needs to be more than simply a review of findings from both your previous chapters. Obviously the chapter can be structured around this but it needs to think more about the implications of your findings, how reserch could usefully take the findings of your thesis forward. It is more an overall 'so what' chapter. Okay, you have done all this fantastic work, but what does it really mean?
I also had a section for overall strengths / weaknesses and tried to tie the whole thesis together. It is also a point for mentioning more recent work in relation to your findings (stuff published since you did your lit review chapter).
Hope this helps! That is what I was told, so of course others may have differing opinions.
