Insulting to one's intelligence, CGI action lame!

There's a lot of things I can say about this, none of them complimentary, but who has the time? Instead I will restrict myself to a few questions I hope someone may answer, so I can maybe have a better appreciation for this mess.
1. Is an army commander allowed to give orders that put the lives of entire nations at risk in order to save his own skin, such as happened when whatever-his-rank-was had a gun to his head by Hobbs, so as to let the bad guy go, so as to possibly save the spouses of those two guys who can't act? Not to mention the troops heavily outnumbering our so-called heroes plus the bad guy. 2. Once he was let go (the baddie at the army base scene), why did they immediately try to recapture him. I mean they had him, then let him go, then immediately tried to recapture him without there being any change in the situation as far as they knew. Did I miss a key detail somewhere there? 3. If a properly forewarned army base is not able to defend itself against a bunch of thieves, what's the point of having such a base? Couldn't they call reinforcements just in case? 4. Why send the worlds most dangerous chip out with the world's most smallest convoy? 5. Why did the baddie put up with such a flaming red security risk in the person of Toretto's presumed-dead-but-alive girlfriend Letty? Why not put a bullet through her head soon as Toretto starts pitching up? Why believe in amnesia? It's not like you can see it. 6. On a related note, the Letty character was actually a genuine baddie. Why was it assumed that we sympathized with her?
There's so many other questions but honestly I don't have the energy.
