My analysis
Cofagrigus (by far the biggest joke ever)--meh, i somewhat see you
Zekrom--wat. no way. i will admit it is not the best legendary I have ever seen but you must concede it is not stupid.
Reshiram--roughly same ^
Landorus (joke)--I think the reason for this is GF is trying too hard to base new pokemon off existing things, like the djinn. I like amorphous pokemon
Kyurem--meh
Tornadus (joke)--understandable
Thundurus (joke)--same ^
Hydreigon--Hmmm, this one is tough. I think they could have gone somewhere with the dark/dragon and/or three heads but the design is somewhat flawed
Mandibuzz--you are correct my good sir
Bisharp--I am not allowed to use the kind of language I would like to in response to this. Bisharp is the most awesome design I have ever seen and I can't imagine why you would say this.
Golurk (looks like a robot)--ok but your point?
Druddigon--yes filler dragon type
Mienshao--hmmm....yes
Accelgor--No. I actually like Accelgor's design and the theory behind its evolution. In general speed-based pokemon appeal to me.
Mienfoo--yes
Cryogonal--I think they could have gone somewhere with this, but the sprite is dissappointing. When I first read its dex entries I was so excited to see it and I was let down
Escavalier--Yes, but they had to put something in the Shelmet/Karrablast/Accelgor line
Vanilluxe--Now I think a lot of people use this to criticize gen 5, but I don't go around railing against Mr. Mime
Reuniclus--No. For a psychic-type it's pretty sweet. I like it.
Gothitelle--yes
Archeops--No, I actually like this one. I know there are other rock/flying but the prehistoric bird was a good idea.
Gigalith--When I imagine a straight-up rock type this is what I imagine. No other design. It is not my fav but I still approve
Swoobat--Correct
Spiritomb--Finally a non-5th gen. I'll have to disagree here. Spiritomb could have had a different name but it is somewhat cool.
Combee--Huh...yea, I guess you're right
