Episode VII (spoilers)

[Anomalocaris]

I think it's totally unbelievable that either Finn or Rey could have stood long against even an injured Ren.  But it is slightly more credible for Finn, presumably a trained fighter, to last a couple of rounds with Ren, than Rey.  

And no, swing a bow staff against desert brigands should not be equivalent to experience with the light saber, any more than playing with nunchakus prepares one to face off against a experience kendo practitioner, at least if everything said about Jedi training in episolds 1-6 is suppose to be more than hot air.

And if reaching into Ren's mind to note that ren feared not being the equal of darth Vader is enough to make Rey ren's equal in all the Jedi tricks, then presumably either obiwan and yoda could have touched Luke's forehead and made his the equal or the superior to Darth Vader.

This is all very sloppy story writing, totally not suitable as anything other than shabbiest possible exploitation of low standards and gullibility of the fan base. A basic quality of a worthy protagonist in any halfway decent story is personal success did not come trivially, if at all. This movie overlooks giving its only worthwhile protagonist this quality, so it is not even a half way decent story. Just a few pews and booms.
