What happened to the 90 minute film?

I finally watched Inglorious Basterds and I enjoyed it, but not enough for me to watch it again. Why? Its too bloody long!! The acting was great, as was the plot, but I'm sorry, 154 minutes is just too much. It is exhausting for my eyes and it wears me out. Two and half hours is a big commitment!

And don't even get me started on Clint Eastwood's films...The Changeling had me bawling, partly because the story is just so horrific, but mainly because IT NEVER ENDS!
