I was quite positive with it when introduced, but it looks to me that its influence is being toned down to keep the flow of the games, which is defeating a big part of its purpose. This is more obvious in the EPL but now it is moving in the CL as well. Whilst everybody agrees that the final decision should be the ref's but when there are 50-50 situations, he should be advised to check on the screen. Yesterday's penalty was a dive for me on slow motion, though this was not so clear at normal speed. Maybe the ref wouldn't have changed his decision, but I don't think it was right for him not to be advised to check.
