Not sure what more people have been expecting.
There were concerns he hasnt been reactive enough this year when we've had bad results... he's changed the system after Watford away and it's worked. Subs still a mild concern, but we arent blessed with £30m players on the bench to change games - we've largely got Championship players (hi Henri...) and kids.
I think if you'd offered us the 12 months we've had so far after the 3-0 shambles at Wigan I don't think there's a single Villa fan that would have said "no thanks". Smith has said himself recently that his teams are usually better in the second half of the season, and that game at Wigan last season was pretty much where it began to move forward (we fought back from 2 down against Hull a week later, beat Ipswich and drew at Reading before losing to WBA prior to the winning run). Beaten 3-0 away and looking utterly hopeless? Sounds familiar...
Its in our nature as football fans to never be happy, so he'll never please all of us all of the time, but we should at least be thankful for the last 12 months or so, because on the whole he's done what we wanted when Bruce left - got us up by playing attacking football with fast play, but he's given us the one thing that we've lacked since it went downhill under MON... we have our pride back. We may still go down (although I personally doubt it), but Aston Villa are back on the national radar for the right reasons.
