Disappointed again. Less so than the last Expendables

Rating: 4/10 (12 April 2013)

I feel that if I were to write a lengthy review, I would have wasted more time on this movie franchise so I am going to keep it as brief as possible. Without giving much away, I just want to help steer clear the guys who are on the fence about wanting to watch this movie and may be looking for a good movie plot.
Although the plot and script are better than the first movie and the lines seem to be a lot less cheesy, it still suffers from the really bad introduction of cameos. It's as if every time they are cornered in the plot, along comes another cameo to pull them out of the ditch. This is one of the reasons although better than the first movie, still a bad script. There needs to be a better build up to events in the plot. Although having said that, the plot is more gripping than the first movie (if only a little).
Questions I need to ask (maybe I missed this from finding it hard to stay awake):
1. Just like in the first movie, if Willis' crew are so tough that they were going to punish Stallone's crew for failing, why not just do the missions themselves?
2. Why would he take on the worst baddies fearlessly and fear the wrath of Willis' crew?
3. Why did Chuck Norris have this giddy little smile throughout his cameo appearance that said he was there to bake muffins rather than be the so-called-lone-wolf?
Plus many more questions I can't be bothered to list.
