I've always enjoyed hearing from Roger Ebert on movies. Of the two (Siskel and Ebert), I always kind of thought that Ebert was more talented. If you haven't read some of his reviews, try some. Even if you don't read anything else he wrote, read Roger Ebert's review of the movie North. Just priceless!
I can't really agree with the assertion that Harrison Ford is a particularly good actor. He's charming as hell and fun to watch, but rarely has he ever done anything resembling actual acting. When I saw the trailer for 42 I was astonished to see that he was actually trying to play a character, instead of just being the sort of Generic Grumpy Harrison Ford Guy we've seen in most movies he's ever been in.
I have to agree somewhat with Benjamin, even though I really like Harrison Ford. I find it quite funny that EotS received so much criticism upon release, but is now considered by many to be the best of the series.
