Nah. There are plenty of modern shows with rubbish CGI. Man, that Terra Nova thing a couple of years back was cringeworthy, and it was touted as all big-budgety and Spielbergy. And the SFX last year (and for the preceding three years) was generally top-notch.
I haven't seen Terra Nova, so dunno. I don't really watch tv anymore. Who; Sherlock; Shield; that's about it.
The sets are generally top-notch; it's the CGI that's lacking.I get the impression that a lot of the SFX budget was saved for the finale. Then again, I don't think they use The Mill any more, so that may be part of it. There are plenty of good effects this year (and the TARDIS interior this year is enormous and gorgeous!)
