Sorry to hear about the project heading in the wrong direction beside your attempts. As many suggested sooner or later things are going to blow up and you need to either be prepared to face the storm since you are acting as a team lead, or simply either move to another group in the company or find a new place by sending your resume around.
When it is going to blow up, and if you are still there I will advise you to keep track of any emails that you may have sent and shared in larger group with your concerns. 
Being able to show some accounting of what happened may help you overall.<p>Personally I will get the hell out of there: it is not worst wasting your time, energy and stress level especially considering what they are doing to your review. Working in a toxic environment is not good in the long term.
