I like the fact that you've thought about the BBC's use of the blocks in promos, I quite like it without the BBC logo! It's a little more simple and I think that it adds something to the overall design.
However, other than that it's a bit of a poor effort. There is really very little content to judge, it's just a couple of quotes and the name of the show. The attention to detail isn't quite up to scratch either, the positioning of the closing quotation marks is different on the two quotes (the second one is higher up in relation to the text). The quotes in themselves aren't particularly inspiring either - while it's true that these quotes feature in the show, I don't really think that they draw you in and really make you want to watch.
To take this further, I'd say that you need to work on developing a short video or at least a series of still shots that visually show the direction of the promo. Another point, I'd rather that the 24 hour clock was used, so I'd rather see "The Weakest Link, Monday 7th January, 17:15" but that's just my personal preference.
Overall though, nice to see a mock of the Weakest Link (I agree it should definitely be brought back
), but I'd say that at the moment, the mock looks unfinished and I'd prioritise adding more content to make it seem more of a finished product.
2/5 at the moment, mainly because it appears unfinished.
