I don't mind bricks. G1 Magnus is one of my favorite figures from that era, and Wingsaber is one of my favorite figures from the Unicron Trilogy. ROTF Powered Up Prime (stupid name) is pretty much a brick, and I like him. as long as they look nice, I'm okay with them once in a while. I'd never tolerate a line full of them again though. probably one of the reasons why I own so few G1 reissues.
Bricks are fine as long as they look good. Bricks like the Firecons sucks just as much as the articulated turds like Backstop.
I can't say that I like my bricks to transform. I think the key to a brick is it's requirement not to move. If you're building a chimney or bbq, you'd want to make sure your bricks are seated well and are level and plumb. If they were to transform, they'd probably bring disasterous results in fire safety. Walls made of bricks shouldn't move or transform either, the structural integrity would be compromised. Use plenty of mortar to secure your bricks. As far as toys, I think the closest we've seen to a brick transformer is Rock Lords, but those were Go-Bots. They were kinda cool.
Bricks or fully-jointed, each is what it is. Both are great when done well, or terrible when done poorly. I do admit toys like Armada Overload and Energon Wing Saber have an odd level of coolness that transcends their inability to do anything other than stand upright or combine with another toy.
I don't care much for bricks at all. Even when I bought some G1 Comemorative Reissues, I was dissappoited that the figures no only looked 20 years old but couldn't move either. What a let down. Although I have been known to lighten up to certain bricks, if they have enough gimmicks. I wouldn't mind getting my hands on a G1 Fortress Maximus. He may be three bricks in one, but he's still three transformers in one.
Fort Max isn't so much of a brick, yeah he could have been better but for his day he has a really good range of movment.
one of my favorite TFs ever was the ultimate brick, made up of a number of slightly smaller but still very blocky bricks. Metroplex! he was totally bricktacular. as loads of astute transfans have pointed out already - being a brick doesn't preclude a toy being awesome, and personally i quite like the chunky aesthetic. Although in fairness there is a flipside to all this cuboid love: g1 ultra magnus. looks badass. isn't.
I wouldn't call metroplex a brick at least not when put up against a lot of the other toys from his time, actually I think metro beats e wingsabre in tearms of points of movement, he's blocky but not a brick, the orginal 4 scrable city teams now they are bricks.
but what articulation he does have is just for the transformation, it's not like you can do much in the way of posing.
I think all the RID autobot brothers used every point of articulation for there transformations, against for his time metroplex is well articulated, he can pose like he's taking a step or throwing a very odd punch, more than any of the seekers or autobot cars can do, hell he's got sixshot beaten aswell doesn't he?
Really, I'm most concerned about articulation above the waist. How the figure can hold its weapon and point it, since most of my figures are displayed standing if displayed. If the legs of a TF can be "latched" together, all the better, more stability. +-MWG-+
I like doing action scenes with my TFs, so bricks aren't good. Though, if it has a brick robot mode and an alt mode full of playability, I'd still get it.
I like well armed bricks, like apex PM Prime. I even like brick minis like Brawn. Give me a brick with an associated characterization that I like, and I'll probably buy it as long as the colors aren't too hideous. G1 Galvatron is a brick, and he's never appealed to me (probably because I always saw him as just an excuse to have to buy another toy - Megatron was still a viable character to me at that point).
I for some reason have never been able to part with G1 toys perhaps it's because I had a few when i was a child and still love them, or... Perhaps it's because back then toys had rubber tires, chrome applications, lead paint, and Dicast Metal Parts. I love me some Lead Paint...thank you China!!!!!
