I just came back with my wife and son of 13 and we all enjoyed it.
Yeah, it's not Oscar stuff but we went in with low expectations but it wasn't that terrible...we had some simple fun....nothing wrong with that.
The best part was after the movie two boys of about 7-8 or so were discussing Sonic, one saying he was his favorite video game character....so I said yeah but Sonic didn't yet exist in 1982, and the other little fellow said....yeah that was what I was about to say to him.....
I asked how they liked the movie and they liked it too....and those kids probably never touched a real arcade classic.
