How would you evaluate it?
Imo I would give it a 3/10 compared to the 90s, 80s, 70s and 60s.
Music wise we've had emo, 80s retrogressive indie, the return of legwarmers, metalcore---Trivium, Nu metal, Limp Bizkit et al, "bling" rap music.
Movies have been good but there haven't been any iconic films like in the 80s with Back to the Future or Robocop. Too many superhero flicks and re-makes but that said there have been quality films-Oldboy, Pans Labyrinth, Kill Bill I suppose. There was also the trend of gore/torture horror films, which imo had no artistic value, although Saw was quite good because it had a plot.
Videogames-meh maybe I've grown out of them, I still enjoy playing something fun but Halo 2 just doesn't compare to the fun and quirkiness of Sega Rally or Virtua Cop. Morrowind was ok but a bit boring. Oblivion I gave up on. Games are still quite good, but I dunno, I get the impression that they've become more homogenized or something, everything is like everything else.
Fashion etc pretty bad.
The rise of social networking sites, youtube.
The Simpsons went really lame, Southpark got better and better.
This decade also witnessed flagrant spending, war and at the tailend a major economic collapse.
Overall I prefered the 90s.
