Wellllllll ... I give it 6.5 out of 10.
The red ARC looks pretty good.
The other 3 ARCs are all right I guess. They used the cruddy old CW mold, but at least they got the correct shade of blue (to match the comics) instead of the greyish-blue tone used on the original release.
The gunner dude looks good (aside from missing the rangefinder), but they got the BFG wrong. The guy with that helmet is supposed to have the quad-cannon:
The rotary BFG belongs to one of the regular helmets:
Then again, wasn't there a rumor of a "Clone Gunner" as an exclusive? Perhaps it will be the quad-cannon guy.
