Depends how old you are if you care about him or not. Siskel and Ebert's reviews were THE movie reviews for everyone back then.. then the internet age came and now everyone's a film critic. But their legacy has lived with the people during the Siskel and Ebert age.
I always liked his reviews even though I didn't necessarily agree with them. They were always very thorough and well thought out. And as Khaid said, back in the 70s, 80s, and 90s in the US, Ebert's review was THE review that everyone went by. If he said a movie sucked or was good, he was pretty much the authority. Before there was Rotten Tomatoes or IMDB, there was Ebert. A bad review from him could quite literally single-handedly sink a movie, because everyone used his thumbs up or thumbs down to determine if a movie was worth seeing, that's how powerful of a critic he was back in the day. But being younger and British, it's probably not something you're going to understand.
I frequently disagreed with Ebert, especially regarding his panning of Blue Velvet. I also didn't care for his extraordinarily arrogant attitude about being intellectually above playing video games. However, I did share his love for classic Japanese films from directors like Kurosawa and Ozu, and Ebert was one of the few popular film critics that gave adequate respect to animated films such as Grave of the Fireflies, my pick for #1 movie of all time. So I had mixed feelings about him I suppose.
The Awakening Really well filmed but it had a confusing cluster of a story. Seems like it could have been a lot better.
It looked really good and the acting was much better than an average horror movie but the story was just a mess. Spoilers I'm a bad ghost, no I'm a good ghost, no I'm a scary ghost, no I'm a friendly ghost. I'm some random guy going to rape you! Maybe you're a ghost. Whats wrong with my leg! Wait, was that a ghost too? I look happy but I'm not and I want to kill myself and maybe I want to touch myself too. Peep hole in the bathroom! The end. /Spoilers 6/10 for me.
Castle of Blood I was expecting some campiness with this one, but it actually turned out to be rather interesting. Probably one of the better "dare you to stay in this haunted house overnight" flicks from the classic era. Really cool black and white lighting as well...very RE in spots. There were some bizarre dub moments though, with entire sequences of Italian dialogue not being dubbed over as they were happening on screen.
The Devil Inside Sooo booring. The last 15 minutes were the best part. Actually the ending might have been the best part because it was over. 3 out of 10 ghosts would like this movie.
Oblivion. Worth it for the visuals alone. By the guy who did Tron Legacy. Story falls flat towards the end but I quite enjoyed it.
Corman's World Interesting documentary about director/producer Roger Corman. I didn't realize that so many "good" directors and actors got their start in Corman's "bad" exploitation flicks: Jack Nicholson, Francis Ford Coppola, Robert DeNiro, Martin Scorcese, Dennis Hopper etc. The segment about how Jaws and Star Wars were the beginning of the end for Corman's style of film was an eye-opener as well. Essentially Hollywood took the B-movie and pumped up the budgets to a level where independents weren't as viable with consumers anymore.
The Constant Gardener I didn't care for it. The ending was lame, the plot undefined and it was mostly boring.
