Inception is a good film la in my opinion. The last 15 minutes is really gripping and have you at the edge of your seat. The part where Cobb woke up at the end is very beautifully done.

Like you i have to go and look for the some answers for the ambigious loopholes..but once you get a clear idea of how the rules work in their world...you will get a better understanding of the movie. I think the haters probably got lost during the show,, hence explains the low scores...
