EDIT: I know I do go on for a page at a time sometimes, but I at least try to break it up and put a few opinions forth, it's not all just a single aimless rant!
I do wonder if it's the 'QI problem' where, and I know it was only suggested but not confirmed, but QI wouldn't get bought for the US market, because they thought Americans wouldn't have any interest in some TV show that told you facts n stuff. Which, I should state my opinion, is bloody ridiculous, and a sure sign of the pitifully low opinions TV execs have of the viewing public.
Why else do they need to remake so many great shows, US shows do just fine in the UK and vice versa, people WILL watch a show with actors using different accents. I understand that maybe 'Roy' has a strong Irish accent for the US market, but apart from that, there shouldn't be any difficulty in enjoying the original, instead of hurling millions at remaking it.
Also, I believe that it's partly the stupid level of model worship going on in US TV. Over in the UK, if someone's good at their job, we tend to let them on TV, tho it is slowly getting worse, with pushing out older female talent in news shows etc. Maybe they think a UK cast is just too hideous and deformed to be on TV, and thus need to recast it with Jersey Shore rejects to make it palatable to the viewers.
Finally, I think there's just a core problem with TV in general, that a show that is mediocre, but innoffensive and appealing to a wide audience, will always get more viewers than a truly brilliant show with a less wide appeal. This means it's in the makers interest to make dull, by the numbers, easily consumable entertainment that doesn't make anyone have to think, over something that'll truly engage the viewer.
for example, QI, a massively successful show, nevertheless started out tucked away on BBC 4, their arts and documentary channel. 'Come Dancing', where D list celebrity jiggle about to badly reworked 'hits' instantly appeared in a prime time slot on BBC 1, their main channel. Don't get me wrong, it's popular, and it's 'good' at what it does, but there's no aiming high involved.
I know I said 'Finally' but another example just came to me. BBC just reincarnated 'Room 101', where special guests would talk about things they hated, and it used to be half an hours banter between the host and guest. The remake is now a 3 guest panel show, 'because panel shows are popular'. This dilutes the input of everyone, and really doesn't give you a chance to get to know the guests, while being more expensive to make and less enjoyable. All because 'Mock the Week is popular, make more panel shows'.
I unfortunately don't see a fix for this.
