About that Super Saiyan God Form. this form has a Big purpose why it looks that way, it has nothing to do with that tori wasn't creative or lazy. He choose to look like this, because he wants to bring back the original Super Saiyan form from the Freeza saga. He wants to ged rid of the Ss2 and 3 for good, because super saiyan 1 is the only Form that acctually has a Story behind it, supposed to be that Legendary Form of A Saiyan.
after goku transformed back from ssgod to normal state, he already became way stronger than in ss3 at his MAX, because his body could experience this form and absorb it and Then, he transformed into a Super Saiyan to match beeruses power again. the same power he had in super saiyan god form
"quote: OK then, how did you come up with Super Saiyan God?
Akira Toriyama: Whis also mentions Super Saiyan God, and I had to reread all of the comics again, then I was able to come up with the idea. I made Super Saiyan God look simple because that’s the Saiyan God. End quote"

"What is Super Saiyan God?!4
[Super Saiyan] God’s appearing was set from the very start of production. There’s a line in the movie, too, but even I thought, “‘God’ is an exaggeration…”. (laughs) As for the design, I made it by taking Super Saiyan, which I’d made flashy up through “3”, and paring it down to the absolute limit."

There is a very good chance that the Ss god won't be seen in the whole story, because in the movie it only lasted for about 10 minutes.
i watch DB since i was 5 and i'm a huge fan of it and i my opinion i like the ss god form rather than to have a golden ss4 version that you might see only for a short time and then never again...
this is toriyamas work, instead crying around about the design, you should ask why he made him look that way and not like maybe some ss4 with golden hair and fur or whats o'ever. and there you have the answers
and after such a long time he is at it again and we should be open for what he has in store for us, and i'm sure it will be just as legendary, as DB and Z was at their springtime
Honestly, i like the what he has done so far with those movies and the series so far and i would love to have en extendet version of BoG and RoF, because he can show so much more in the series than he can in a movie. because he doesn't need to worry about keeping the time line for a movie. but that's just my thoughts
