I find all of woody allen flicks interesting. Always an interesting subject no matter how good bad ugly great the movie is. This new one is no exception.
MITM is a totally pleasant whimsical delight... the actors are charming especially Emma Stone and Eileen Atkins as Colin Firth's aunt.
The humor is very light... whimsy is a good term... is it funny? For me NO... but it's also not unfunny. It's just this one long smile.
The scenery is gorgeous.
The story is smart hidden in a cute jacket.
The age difference between the two is maybe a tad much but the rom in this romcom is not the leading factor... at least for most of it. Maybe a Colin Firth from 15 years ago would have been a better lead but unless Woody has access to that time travel device in Midnight In Paris that was not an option.
As with some other Allen films there is a turn in direction at some point. Won't give anything away. Your enjoyment of the movie might hinge on how you feel after it goes after this point.
For me it may have lingered around too long towards the end.
Firth is good and likable but I did find some of his character's decisions to be too abrupt. But maybe that's just me. And some of his duologue felt a bit rushed and acted.
I wouldn't personally rank this as one of his recent greats like Paris, Jasmine, Match Point or VCB... but it's a fun summery concoction of scenery, whimsy and costumes.
