What a boring, weird, let down of a movie
After they recapped the ending showing us what things were done, which was so predictable as to it being him, there were so many scenes that were pure luck to the plot.
The bike, there's no way Oliver would have known Felix was just going to be sitting there waiting on the side of the road like a damsel in distress. The bar tab. There would have been no way him being able to know of all the people drinking at the bar that Felix was going to be the one to pay the tab.
OK so he has siblings and parents that weren't junkies. How did that fit into the movie at all? Why did he need to run with that lie? Felix didn't need to hear that to befriend him. Oliver was still a weirdo.
Other than that at what point did he target Felix and his family and why?
Lastly, why did we need to see his weenie?
