While I won't say the art sucks, as it definitely has it's strong points and is consistent, I will say that it is kind of grating on me.
I don't think it has anything to do with an "anime" style in general. I mean come on, if a new artist jumped on the book and made it look remeniscient of Cowboy Bebop or something, we'd probably all be ecstatic!
Now, it is obvious the guy is influenced by anime/manga, but I think he is leaning too far into the cutesy pokemon/youth type of anime as opposed to something we would probably all really dig, like a Ghost in the Shell, or the aforementioned Cowboy Bebop style.
Spider-Man Loves Mary Jane had a very anime flavored style (at least for a while there until Terry Moore started doing the writing. I forget the new artist's name) and it was pretty darn spectacular. Had USM looked anything like that, I would have been extremely happy.
I personally think that Immonen was the best artist on the book by far and it'll be hard to top him, as I think he just had a pitch perfect feel for the chracters. I don't hate LaFuente's style, I just don't think it was the best choice for the book.
Likewise, there are certain things about the story so far I can't get behind. Mostly Gwen and Peter being together. What is with this sudden desire to rip comics' Golden Couple apart?! Even more than Clark and Lois, I think Peter and MJ are the quintessential couple in comics.
With how Gwen was established as more of a sister figure to Peter, it's quite awkward to all of a sudden see her and Pete as a couple, especially with no explanation.
Johnny seems kind of awkwardly placed as well.
I have to say what some of the others are saying. I bought the first issue, read the second in the shop, but I think I'll wait for the graphic novel now to see how everything shapes up and just get story tid bits from the interwebs. Kinda sucks, cause I had only read off and on when Bagely was doing it, partly because I couldn't dedicate the money to pick it up. I would just read it in the bookstores and such. When Immonen joined though, I just fell so in love with his art that while I couldn't get it monthly, I got all the graphic novels of his issues and I did get his stuff during Ultimatum.
I hope USM is able to pull something a little more solid together soon. It's hard to find a good Spidey book nowadays, and I'd hate to put this down. Heck, even though I have been enjoying Ultimate Avengers, the art has been feeling a little lacking. Not as much as USM, but still. It's hard to follow up guys like Immonen, Hitch, and I suppose even Bagely, but I can't help feeling that there were better guys for the job out there somewhere.
