Shoulda been just one Wedding Crasher
Vince Vaughn and Isla Fisher were great together. It was very believable that an obsessive little nutjob like her would fall for a lying con man like him. Their story was funny, and all the best scenes revolved around them.
Compare that to Owen and Rachel McAdam. Very weak and unbelievable writing here. Claire was smart and savvy and pretty, and no way in a million years would she fall for a lying con man with that broken nose. Drug my boyfriend? It's ok. Lie to me? No problem. Ruin my sister's wedding and give a speech in the middle of the aisle? Fine with me. The Owen scenes are the ones we fast-forward over, not the Vince scenes. Woulda been so much stronger without him.
