To be honest, I didn't really expect much from this flick but since the previous installments involving Robert Langdon were actually watchable, I thought I might as well give it a try. Well, even though it was not awful, I still had a hard time to care about the damned thing, I'm afraid. First of all, the twist concerning one of the main characters was actually fairly easy to figure out. At least, it was fun to follow once again Robert Langdon trying to solve one of his elaborate puzzles and I always had a weak spot about movies dealing with amnesia. Unfortunately, the whole trick about giving Robert Langdon some hallucinogenic drug was just rather ridiculous. I mean, sure, it will mess around his mind and his memory but how can you predict what he will eventually remember and when he will get back his memories? And, of course, as usual with these kind of movies clouded with mystery, at some point, they had to uncover what was actually going on and, to be honest, the end-result was so far-fetched and rather ridiculous. Seriously, I don't think much of it actually made sense. Maybe I should read the book at some point to see if it works better (they apparently did make some modifications for the movie) but, with Dan Brown, I highly doubt it. Anyway, to conclude, if you don't analyse it too much, it is not so bad but I will certainly forget the whole thing fairly quickly which is never really a good sign.
