That movie was so bad that it took me almost 3 hours to watch it. Because I had to keep taking breaks. Because it was so terrible. Aside from the weak "plot", here are some other things:

~ terrible acting by almost everyone, even actors I normally like- it's like they knew it didn't matter, given the script
~ very close to the beginning, they're in a club and Adam says "She doesn't look like she wants to be bothered" and Mike says "Look at what she's wearing. She came here hoping to be bothered." NO. GROSS. This is disgusting and men need to get over themselves, jfc. And then two minutes later, these girls accept shots handed to them by a man they just met, which contain who knows what and which were not made in front of them. This entire scene is a PSA of what not to do, for everyone involved.
~ at one point Dallas says, with absolute sincerity, "F--k that mirror like you mean it."
~ Is Matthew McConaughey contractually obligated to say "alright alright alright" in every movie now? Come on.

Merely 20 minutes in I decided to hate-watch it all the way through and now I deeply regret it, and I'm angry.
