After some days with the new format I find it not bad - even though I liked the former, simplistic format, too, because it kept blatant visuals (e. g. signatures with graphics that occupy half the visible page - with EVERY post) at bay.
Only sad thing so far is for me that profile information or the ignore list have gone blank. I am also a bit confused by new reviews appearing under the latest forum entry list, too.
Handling, e.g. editing the profile, is a bit complicated (might be a browser issue on my side, though), but nothing that could be called rocket science.
Having the site "fit for the future" is IMHO worth the change.
